Description: STRINGED INSTRUMENT TUNER HOLDER This application claims the benefit of United States Provisional Application No. 60/237,336, filed October 2, 2000. FIELD OF THE INVENTION The present invention relates to stringed instrument tuner holders, and more specifically guitar tuner holders. BACKGROUND Stringed instruments, such as guitars, are typically tuned through the use of an electronic tuner which is capable of detecting the frequency of vibration generated by plucking, striking, or stroking a single string on the instrument and communicating any difference between the frequency of the generated vibration and a target frequency on a standard musical scale. When using a tuner, it is necessary to position the tuner so that the visual tuning display, which communicates the difference between the frequency of the generated vibration and the target frequency, is visible to the person tuning the instrument. It is also generally desired to position the tuner close to the sound hole of the instrument with the transducer (e.g., a microphone) facing the sound hole in order to maximize reception of sound from the instrument while minimizing any external interference. In an effort to attain these goals while also keeping both hands free to hold, play and tune the instrument, a number of tuner holders have been developed. United States Patent No. 5,728,959 describes a clamping holder for a tuner for mounting a tuner on a microphone stand. While effective for positioning the tuner so that the visual tuning display is visible to the person tuning the instrument and the transducer faces the sound hole of the instrument, the tuner is mounted a significant distance from the sound hole of the instrument. United States Patent No. 4,899,636 describes a guitar tuner, which incorporates a suction cup to mount the tuner to the guitar body. While generally effective for allowing positioning of the tuner proximate the sound hole with the transducer facing the sound hole and the visual tuning display viewable by the person tuning the guitar, guitar owners are very reluctant to attach such a device to the body of their guitar due to the high probability that the suction cup will mark, scratch, or otherwise damage the guitar body. United States Patent Des. 353,826 depicts a guitar tuner holder configured and ananged for suspending a platform from the sound hole of a guitar. The holder includes a centrally located upper knob extending downward from the back edge of the platform for engaging the inner surface of the guitar body through the sound hole, and a pair of laterally spaced lower knobs extending rearward from right and left legs for engaging the outer surface of the guitar body immediately below the sound hole. While generally effective for allowing positioning of the tuner proximate the sound hole in an orientation which allows the person tuning the guitar to view the visual tuning display of the tuner, the platform extends sfraight out from the sound hole resulting in a positioning of the tuner immediately in front of the guitar strings such that the tuner interferes with playing of the guitar strings and the transducer is positioned above at least some of the guitar strings. Accordingly, a need exists for a tuner holder which positions a tuner proximate the sound hole of a stringed instrument with the transducer facing the sound hole and the visual tuning display viewable by the person tuning the instrument, without interfering with playing of the instrument. SUMMARY OF THE INVENTION The invention is an inexpensive tuner holder for stringed instruments capable of positioning a tuner proximate the sound hole of the instrument with the transducer facing the sound hole and the visual tuning display viewable by the person tuning the instrument, without interfering with playing of the instrument strings.

Construction The invention is suitable for use in connection with a wide variety of stringed instruments so long as the instrument has a sound hole from which the invention may be suspended, including specifically, but not exclusively, dulcimers, guitars, harps, mandolins, and ukuleles. Since the invention is particularly suited for use in connection with guitars, the balance of the disclosure shall be based upon use of the invention in connection with the tuning of a guitar, without any intent to limit the claims to guitar tuners or the tuning of guitars. First Embodiment Referring generally to Figures 1-13, a first embodiment of the invention is a guitar tuner holder 10, which includes a strut 20, a shelf 30, and a hook 40. The strut 20 extends in a fransverse direction z with a distal edge 21 transversely spaced in a second fransverse direction z 2 from a proximal edge 22. The strut 20 may be sized, shaped and configured as desired so long as the strut 20 extends in a transverse direction z, is capable of securely supporting a tuner 500 placed upon the shelf 30, and capable of withstanding normal wear and tear. Acceptable configurations of the strut 20 include specifically but not exclusively, a rectangular plane, a triangular plane, an ornamentally shaped plane, a framework of stiles and rails, an ornamental framework, a single central beam, a Y-shaped split beam, etc. The strut 20 preferably has a transverse height of 2 to 5 cm and a lateral width of 1 to 10 cm. In a prefened embodiment, the strut 20 defines a first major surface 23 facing a first longitudinal direction x 1 and a second major surface 24 facing a second longitudinal direction * The shelf 30 extends substantially perpendicular in the first longitudinal direction x 1 from the distal edge 31 of the strut 20, with a proximal edge 32 of the shelf 30 connected directly or indirectly to the distal edge 21 of the strut 20 and a distal edge 31 of the shelf 30 longitudinally spaced from the proximal edge 32 of the shelf in the first longitudinal direction x 1 . The shelf 30 may be sized, shaped and configured as desired so long as the shelf 30 extends in a first longitudinal direction x 1 from the strut 20, is capable of securely supporting a tuner 500 placed upon the shelf 30, and possesses a structural integrity sufficient to withstand normal wear and tear. Acceptable configurations of the shelf 30 include specifically but not exclusively, a rectangular plane, a triangular plane, an ornamentally shaped plane, a f amework of stiles and rails, an ornamental framework, a Y-shaped split beam, etc. The shelf 30 preferably has a lateral width of 1 to 10 cm and a longitudinal depth of 3 to 10 cm. In a prefened embodiment, the shelf 30 defines a first major surface 33 facing a first fransverse direction z 1 and a second major surface 34 facing a second fransverse direction z 2 . The hook 40 extends in a second longitudinal direction x 2 from the proximal edge 22 of the strut 20 and defines a concavity 49 open towards the distal edge 21 of the strut 20 (i.e., accessible in a first fransverse direction z 1 ). The hook 40 is preferably laterally elongated so as to provide at least two laterally spaced points of contact (unnumbered) between the hook 40 and a guitar body 401 when the holder 10 is suspended from the sound hole 402 of the guitar 400 so as to increase the lateral direction y stability of the suspended holder 10. The hook 40 preferably has a lateral width of 2 to 5 cm and a longitudinal depth of 1 to 2 cm. The longitudinal depth of the concavity 49 defined by the hook 40 is preferably greater than the thickness of a standard guitar body 401 at the sound hole 402 in order to simplify hooking of the holder 10 onto a guitar body 401 and prevent the exertion of any clamping force upon a guitar body 401 by the hook 40 which could result in damage to the surface finish of the guitar body 401. Due to the oversized nature of the concavity 49, the holder 10 will tend to "lean" forward from a guitar body 401 when the holder 10 is suspended from the sound hole 402 of the guitar 400, causing the shelf 30 to extend at a slight downward angle relative to a guitar body 401 (i.e., the first major surface 33 of the shelf 30 forms an angle of slightly more than 90° (e.g., commonly between about 100° to 120°) with the face (unnumbered) of the guitar body 401). In order to return this angle closer to 90°, the holder 10 preferably includes a protuberance 50 which extends in the second longitudinal direction x 2 from proximate the distal edge 21 of the strut 20. In a prefened aspect, the protuberance 50 extends a distance in the second longitudinal direction x 2 sufficient for causing the shelf 30 to extend at a slight upward angle relative to a guitar body 401 when the holder 10 is suspended from the sound hole 402 of the guitar 400 (i.e., the first major surface 33 of the shelf 30 forms an angle of slightly less than 90° (e.g., between about 70° to 80°) with the face (unnumbered) of the guitar body 401). By causing the shelf 30 to extend at a slight upward angle from the guitar body 401, the transducer 501, typically a microphone, and transducer sound opening 519 in a tuner 500 supported by the holder 10 will more directly face the guitar strings 410a-f and sound hole 402 of the guitar 400 and thereby improve the reception of sound emanating from the guitar 400 by the fransducer 501, while also causing the visual tuning display 502 on the tuner 500 to more directly face the person (not shown) holding and tuning the guitar 400 and thereby facilitate viewing of the visual tuning display 502 during tuning of the guitar 400. The protuberance 50 may be a single bump centered laterally on the strut 20, a pair of laterally spaced bumps, a plurality of laterally and transversely spaced bumps, a laterally elongated ridge, or any number of other structures effective for achieving the desired angling of the shelf 30. The protuberance 50 preferably has a longitudinal depth of 0.3 to 1 cm. The holder 10 preferably includes a securing means 70 for securing a tuner 500 to the holder 10. As shown in Figures 7 through 11, an exemplary means 70 for securing a tuner 500 to the holder 10 is hook and loop tape 71. The hook and loop tape 71 includes (i) a first portion 71a (i.e., either the hook portion or the loop portion) adhesively bonded to the holder 10, (ii) a second portion 71b (i.e., the hook portion or loop portion which is complimentary to the first portion 71 ) which is releasably attached by the connective effect of the hook and loop tape 71 to the first portion 71a, and (iii) a release liner 71 r covering the pressure sensitive adhesive coated exposed major surface (unnumbered) of the second portion 71b. The release liner 71 r can be removed for subsequent adhesive attachment of the second portion 71b of the hook and loop tape 71 to a tuner 500. The hook and loop tape 71 is preferably attached to the first major surface 23 of the strut 20 proximate the first major surface 33 of the shelf 30. Such a positioning of the hook and loop tape 71 allows a tuner 500 to be attached to the holder 10 by longitudinally sliding the tuner 500 along the first major surface 33 of the shelf 30 in the second longitudinal direction x 2 until the second portion 71b of the hook and loop tape 71 adhered to the timer 500 contacts the complimentary first portion 71a of the hook and loop tape 71 adhered to the holder 10. Detachment of the tuner 500 can be achieved by holding the tuner 500 in one hand (not shown) and the holder 10 in the other (not shown) and then pulling the tuner 500 and holder 10 in opposite longitudinal directions x 1 and x 2 respectively. As shown in Figures 8, 10 and 11, a layer of protective padding 60 is preferably placed over those portions of the holder 10 which contact the body 401 of a guitar 400 when the holder 10 is suspended from the guitar body 401 proximate the sound hole 402 in the guitar 400. The desired protection can generally be achieved by providing a layer of protective padding 60 over at least a portion of the second major surface 24 of the strut 20, at least a portion of the interior major surface 44 of the hook 40, and at least a portion of any protuberance 50 including at least the apex (unnumbered) of the protuberance 50. In order to maximize protection afforded by the protective padding 60, it is generally desired to provide a layer of protective padding 60 over the entire second major surface 24 of the strut 20, the entire second major surface 34 of the shelf 30, the entire interior major surface 44 of the hook 40, and the entire exposed surface area of any protuberance 50. Materials suitable for use as protective padding 60 include any material effective for protecting the surface finish of a guitar body 401 from scuffmarks, abrasions and scratches include specifically, but not exclusively, felt, foamed thermoplastics, low durometer rubber, foamed rubber, etc. Selection of a suitable material for use as protective padding 60 is well within the competency of those having ordinary skill in the art. As shown in Figure 12, the holder 10 may optionally include a retaining wall 80 extending in the first fransverse direction z 1 from the shelf 30 proximate the distal edge 31 of the shelf 30 for forming a retention channel 89 with the strut 20 and shelf 30 effective for improving retention of a tuner 500 on the shelf 30 during tuning. The proximal edge 82 of the retaining wall 80 is coupled directly or indirectly to the shelf 30 with the distal edge 81 of the retaining wall 80 extending from the proximal edge 82 of the retaining wall 80 in the first transverse directions z 1 . When the holder 10 includes a retaining wall 80, holder 10 is preferably configured, ananged, and constructed from a material which allows the retaining wall 80 to be elastically deflected away from the strut 20 so that a tuner 500 may be (i) inserted into the retention channel 89 by deflection of the retaining wall 80 from a normally closed position nearer the strut 20 to an open position further from the strut 20 and dropping the tuner 500 into the open retention channel 89, (ii) retained within the retention channel 89 by allowing the deflected retaining wall 80 to return to the closed position, and (iii) removed from the retention channel 89 by deflection of the retaining wall 80 from the normally closed position nearer the strut 20 to the open position further from the strut 20 and lifting the tuner 500 from the open retention channel 89. As shown in Figure 12, retention of a tuner 500 within the retention channel 89 may be further enhanced by providing (i) a first longitudinally extending ridge or finger 83 proximate the distal edge 81 of the retaining wall 80 which extends in the second longitudinal direction x 2 into or over the retention channel 89, and/or (ii) a second longitudinally extending ridge or finger 84 extending from the strut 20 in the first longitudinal direction x 1 into or over the retention channel 89. The strut 20, shelf 30, hook 40, protuberance 50, and retaining wall 80 may be constructed from the same or different materials. The strut 20, shelf 30, hook 40, protuberance 50 and retaining wall 80, or various combinations thereof, are preferably integrally formed from a single mass of material as a single unitary article. Materials from which the strut 20, shelf 30, hook 40, protuberance 50 and retaining wall 80 may be constructed include any material having the necessary structural integrity including specifically, but not exclusively: metals such as aluminum and steel; paper products such as cardboard and cardstock; plastics such as polyethylene and polyurethane; natural and synthetic rubbers; and wood. Selection of a suitable material is well within the competency of those having ordinary skill in the art. As shown in Figures 7 through 11, a fransducer 90, such as a microphone or piezoelectric sensor, may be permanently or releasably attached to the holder 10. An electrical contact 91 is electrically connected to the fransducer 90 via electrical leads 92. The electrical contact 91 is configured and ananged to engage a mated electrical contact (not shown) on a tuner 500 retained by the holder 10. The electrical contact 91 on the holder 10 can be configured and ananged relative to the electrical contact (not shown) on the tuner 500 such that engagement of the contacts is effected automatically upon connection of the tuner 500 to the holder 10. Alternatively, the electrical contact 91 on the holder 10 can be configured and ananged relative to the electrical contact (not shown) on the tuner 500 such that engagement of the contacts requires manual manipulation of one or both of the electrical contacts after the tuner 500 is connected to the holder 10 (e.g., insertion of a male plug 91 at the end of an insulated electrical cord (unnumbered) extending from the holder 10 into a female input port (unnumbered) in the tuner 500). The fransducer 90 can be positioned substantially anywhere on the holder 10, with a preference for the first major surface 33 of the shelf 30. The fransducer 90 is effective for sensing any vibration generated by the playing of a guitar string 410a-f, and converting the sensed vibration to an electrical signal having a value representative of the frequency of the sensed vibration. The electrical signal generated by the transducer 90 is fransmitted to the tuner 500 through the electrical leads 92 and electrical contact 91. The tuner 500 is able to utilize the electrical signal received from the fransducer 90 to generate a perceptible signal (i.e., a value on a visually perceptible pitch meter) indicating any difference between the frequency of the sensed vibration and a target frequency on a standard musical scale. As shown in Figures 14 through 22, the holder 10 can be constructed with a laterally extending rotation channel 39 along the inside juncture of the strut 20 and the shelf 30, and a means for securing a tuner 500 to the holder 10 which allows pivoting of the tuner 500 about a lateral axis 30y as between a storage position, shown in Figure 21, and a tuning position, shown in Figure 22. When in the storage position, the front face 511 of the tuner 500 (i.e., the face having the visual tuning display 502) faces and rests against the first major surface 23 of the strut 20 (e.g., the front face 511 of the tuner 500 is substantially parallel to the first major surface 23 of the strut 20). When in the tuning position, the back face 512 of the tuner 500 faces and rests against the first major surface 33 of the shelf 30 (e.g., the front face 511 of the tuner 500 is substantially perpendicular to the first major surface 23 of the strut 20). A tuner 500 can be pivotally attached to the holder 10 in any number of ways known to those skilled in the art. As shown in Figures 14, 15 and 17, one such nonlimiting example is an axial-direction-locking cylindrical electrical contact 91 laterally extending from one side of the holder 10 into the rotation channel 39 for releasably engaging an electrical input port (not shown) in the tuner 500. The electrical contact 91 restricts lateral direction y movement of the tuner 500 relative to the holder 10 while permitting relatively unrestricted rotation of the tuner 500 about a lateral axis 30y. Second Embodiment Referring generally to Figures 23-32, a second embodiment of the invention is a guitar tuner holder 100, which includes an enclosure 110 and a hook 140. The enclosure 110 has a longitudinally spaced front 111 and back 112, a transversely spaced top 113 and bottom 114, and a laterally spaced right side 115 and left side 116. The enclosure 110 defines a retention chamber 119. A first access opening 117' into the retention chamber 119 is provided through the top 113 of the enclosure 110. A second access opening 117" into the retention chamber 119 is provided through the front 111 of the enclosure 110. As shown in Figures 23 and 31, the first access opening 117' through the top 113 of the enclosure 110 is configured and ananged to permit a major portion of a given guitar tuner 500 to be slidably infroduced and engaged within the retention chamber 119 in a storage orientation. As shown in Figures 23 and 32, the second access opening 117" through the front 111 of the enclosure 110 is configured and ananged to permit a minor portion of the same given guitar tuner 500 to be slidably introduced and engaged within the retention chamber 119 in a tuning orientation. The second access opening 117" through the front 111 of the enclosure 110 is preferably transversely located proximate the bottom 114 of the enclosure 110. As shown in Figure 23, a transversely extending slot 118 is preferably provided through the front 111 of the enclosure 110 from the first access opening 117' to the second access opening 117" to facilitate removal of a tuner 500 stored within the retention chamber 119. The walls of the enclosure 110 may be formed as a solid wall or an open framework, so long as the enclosure 110 is capable of securely retaining a given guitar tuner 500 in the storage and tuning positions. The size and shape of the retention chamber 119 is preferably selected to mate with a given tuner 500. Generally, an appropriate fit can be achieved with a retention chamber 119 having a transverse height of 4 to 12 cm, a lateral width of 3 to 12 cm, and a longitudinal depth of 1 to 4 cm. More specifically, a transverse height of 6 to 10 cm, a lateral width of 4 to 6 cm, and a longitudinal depth of 2 to 3 cm will provide an appropriate fit with most commercially available tuners 500. The hook 140 extends in a second longitudinal direction x 2 from the enclosure 110 away from the retention chamber 119 and defines a concavity 149 open towards the bottom 114 of the enclosure 110 (i.e., accessible in a first fransverse direction z 1 ). The hook 140 preferably extends from the back 112 if the enclosure 110 proximate the top 113 of the enclosure 110, and most preferably transversely extends a distance above the top 113 of the enclosure 110 in the first fransverse directions z 1 as well as a distance in the second longitudinal direction x 2 . The hook 140 is preferably laterally elongated so as to provide at least two laterally spaced points of contact (unnumbered) between the hook 140 and a guitar body 401 when the holder 100 is suspended from the sound hole 402 of the guitar 400 so as to increase the lateral direction y stability of the suspended holder 100. The hook 40 preferably has a lateral width of 2 to 5 cm and a longitudinal depth of 1 to 2 cm. The longitudinal depth of the concavity 149 defined by the hook 140 is preferably greater than the thickness of a standard guitar body 401 at the sound hole 402 in order to simplify hooking of the holder 100 onto a guitar body 401 and prevent the exertion of any clamping force upon a guitar body 401 by the hook 140 which could result in damage to the surface finish of the guitar body 401. Due to the oversized nature of the concavity 149, the holder 100 will tend to "lean" forward from a guitar body 401 when the holder 100 is suspended from the sound hole 402 of the guitar 400, causing the bottom 114 of the enclosure 110 to extend at a slight downward angle relative to a guitar body 401 (i.e., the inner major surface 114a of the bottom 114 of the enclosure 110 forms an angle of slightly more than 90° (e.g., between about 100° to 120°) with the face (unnumbered) of the guitar body 401). In order to return this angle closer to 90°, the holder 100 preferably includes a protuberance 150 which extends in the second longitudinal direction x 2 from proximate the bottom 114 of the enclosure 110. In a prefened aspect, the protuberance 150 extends a distance in the second longitudinal direction x 2 sufficient for causing the bottom 114 of the enclosure 110 to extend at a slight upward angle relative to a guitar body 401 when the holder 100 is suspended from the sound hole 402 of the guitar 400 (i.e., the inner major surface 114a of the bottom 114 of the enclosure 110 forms an angle of slightly less than 90° (e.g., between about 70° to 80°) with the face (unnumbered) of the guitar body 401). By causing the bottom 114 of the enclosure 110 to extend at a slight upward angle from the guitar body 401, the transducer 501, typically a microphone, and fransducer sound opening 519 in a tuner 500 retained within the holder 100 in the tuning orientation will more directly face the guitar strings 410a-f and sound hole 402 of the guitar 400 and thereby improve the reception of sound emanating from the guitar 400 by the fransducer 501, while also causing the visual tuning display 502 on the tuner 500 to more directly face the person (not shown) holding and tuning the guitar 400 and thereby facilitate viewing of the visual tuning display 502 during tuning of the guitar 400. The protuberance 150 may be a single bump centered laterally on the enclosure 110, a pair of laterally spaced bumps, a plurality of laterally and transversely spaced bumps, a laterally elongated ridge, or any number of other structures effective for achieving the desired angling of the bottom 114 of the enclosure 110. The protuberance 150 preferably has a longitudinal depth of 0.3 to 1 cm. As shown in Figures 28 and 29, a layer of protective padding 160 is preferably placed over those portions of the holder 100 which contact the body 401 of a guitar 400 when the holder 100 is suspended from the guitar body 401 proximate the sound hole 402 in the guitar 400. The desired protection can generally be achieved by providing a layer of protective padding 160 over at least a portion of the exterior major surface 112b of the back 112 of the enclosure 110, at least a portion of the interior major surface 144 of the hook 140, and at least a portion of any protuberance 150 including at least the apex (unnumbered) of the protuberance 150. In order to maximize protection afforded by the protective padding 160, it is generally desired to provide a layer of protective padding 160 over the entire exterior major surface 112b of the back 112 of the enclosure 110, the entire exterior major surface 114b of the bottom 114 of the enclosure 110, the entire interior major surface 144 of the hook 140, and the entire exposed surface area of any protuberance 150. Materials suitable for use as protective padding 160 include any material effective for protecting the surface finish of a guitar body 401 from scuffmarks, abrasions and scratches include specifically, but not exclusively, felt, foamed thermoplastics, low durometer rubber and foamed rubber, etc. Selection of a suitable material for use as protective padding 160 is well within the competency of those having ordinary skill in the art. The enclosure 110, hook 140 and protuberance 150 may be constructed from the same or different materials. The enclosure 110, hook 140 and protuberance 150, or various combinations thereof, are preferably integrally formed from a single mass of material as a single unitary article. Materials from which the enclosure 110, hook 140 and protuberance 150 may be constructed include any material having the necessary structural integrity including specifically, but not exclusively: metals such as aluminum and steel; paper products such as cardboard and cardstock; plastics such as polyethylene and polyurethane; natural and synthetic rubbers; and wood. Selection of a suitable material is well within the competency of those having ordinary skill in the art. As shown in Figures 28, 29 and 30, a fransducer 190, such as a microphone or piezoelectric sensor, may be permanently or releasably attached to the holder 100. Electrical contacts 191 are electrically connected to the fransducer 190 via electrical leads 192. The electrical contacts 191 are configured and ananged to engage conesponding electrical contacts (not shown) on a tuner 500 when the tuner 500 is retained within the retention chamber 119 in the tuning orientation. The electrical contacts 191 on the holder 100 can be configured and ananged relative to the electrical contacts (not shown) on the tuner 500 such that engagement of the contacts is effected automatically upon placement of the tuner 500 within the retention chamber 119 in the tuning orientation. Alternatively, the electrical contacts 191 on the holder 100 can be configured and ananged relative to the electrical contacts (not shown) on the tuner 500 such that engagement of the contacts requires manual manipulation of one or both sets of electrical contacts 191 after the tuner 500 is placed within the retention chamber 119 in the tuning orientation (i.e., insertion of a male plug (not shown) at the end of an insulated electrical cord (not shown) extending from the holder 100 into a female input port (not shown) in the tuner 500). The fransducer 190 can be positioned substantially anywhere on the holder 100, with a preference for the exterior major surface 112b of the back 112 of the enclosure 110. The fransducer 190 is effective for sensing any vibration generated by the playing of a guitar string 410a-f, and converting the sensed vibration to an electrical signal having a value representative of the frequency of the sensed vibration. The electrical signal generated by the transducer 190 is fransmitted to the tuner 500 through the electrical leads 192 and electrical contacts 191. The tuner 500 is able to utilize the electrical signal received from the transducer 190 to generate a perceptible signal (i.e., a value on a visually perceptible pitch meter) indicating any difference between the frequency of the sensed vibration and a target frequency on a standard musical scale. Third Embodiment Referring generally to Figures 33-44, a third embodiment of the invention is a tuner holder 210, which includes a strut 220, a connection element 230, and a hook 240. The strut 220 extends in a transverse direction z with a distal edge 221 transversely spaced in a second transverse direction z 2 from a proximal edge 222. The strut 20 may be sized, shaped and configured as desired so long as the strut 220 extends in a transverse direction z, is capable of securely supporting a tuner 500 attached to the connection element 230, and is capable of withstanding normal wear and tear. Acceptable configurations of the strut 220 include specifically but not exclusively, a rectangular plane, a rectangular plane with longitudinally extending side legs, a triangular plane, an ornamentally shaped plane, a framework of stiles and rails, an ornamental framework, a single cenfral beam, a Y-shaped split beam, etc. The strut 220 preferably has a transverse height of 2 to 5 cm and a lateral width of 1 to 10 cm. In a prefened embodiment, the strut 220 includes (i) a cenfral wall 220c defining a first major surface 223 facing a first longitudinal direction x 1 and a second major surface 224 facing a second longitudinal direction x 2 , and (ii) laterally spaced right 220r and left 220s sidewalls extending in the first longitudinal direction x 1 from the right and left sides (unnumbered) of the central wall 220c respectively, for facilitating pivotable attachment of the connection element 230 to the strut 220. The connection element 230 is pivotally attached to the strut 220 proximate the distal edge 221 of the strut 220 for pivoting about a lateral axis 230y as between at least a storage position, shown in Figure 42, and a tuning position shown in Figure 43. In the storage position, the front face 511 of the tuner 500 (i.e., the face having the visual tuning display 502) faces and abuts the first major surface 223 of the central wall 220c of the strut 220 (i.e., the front face 511 of the tuner 500 is substantially parallel to the first major surface 223 of the cenfral wall 220c of the strut 220). In the tuning position, the front face 511 of the tuner 500 extends in a first longitudinal direction x 1 from the cenfral wall 220c of the strut 220 facing the first fransverse direction z 1 (i.e., the front face 511 of the tuner 500 is substantially perpendicular to the first major surface 223 of the central wall 220c of the strut 220). The connection element 230 is preferably also pivotable about the lateral axis 230y into a display position, shown in Figure 44, where the front face 511 of the tuner 500 is positioned so as to extend in both a second longitudinal direction x 2 and a first transverse direction z 1 from the lateral pivot axis 230y, and angularly face both the second longitudinal direction x 2 and the second transverse directions z 2 (i.e., the front face 511 of the tuner 500 is positioned at an angle of about 20° to 70° from the second major surface 224 of the cenfral wall 220c of the strut 220). When the connection element 230 is pivoted into the display position, the strut 220 functions as a stand for the tuner 500 such that the holder 210 can placed face down on a flat surface (not shown) with the front face 511 of the tuner 500 extending upward from the surface (not shown) at an angle which facilitates hands-free viewing of the visual tuning display 502. The connection element 230 can be pivotally attached to the strut 220 in any number of ways known to those skilled in the art. As shown in Figure 34, one such nonlimiting example is a cylindrical pin 281 laterally extending from each side (unnumbered) of the connection element 230 proximate the proximal edge 233 of the connection element 230, wherein each pin 281 is mated with a circular orifice 282 in the right 220r and left 220s sidewalls of the strut 220. One or more laterally extending ribs 283 can be provided around each pin 281 for selectively mating with one of a series of angularly offset slots 284 circumferentially positioned around each circular orifice 282 for disengagably preventing continued rotation of the connection element 230 at each of the storage, tuning and display positions, as well as any other desired rotational position. The connection element 230 preferably has a lateral width of 1 to 10 cm and a longitudinal depth of 3 to 10 cm. The holder 210 includes a means 270 for releasably securing a tuner 500 to the connection element 230. As shown in Figures 33 and 34, an exemplary means 270 for securing a tuner 500 to the connection element 230 is a holding channel 239 configured and ananged to frictionally engage an end (unnumbered) of a tuner 500 within the holding channel 239. Retention of a tuner 500 within the holding channel 239 can be further facilitated through the use of an axial-direction locking cylindrical electrical contact 291 extending from the connection element 230 into the holding channel 239 for mated engagement with an input port (not shown) in a tuner 500 when the tuner 500 is slid into the holding channel 239. Alternatively, the connection element 230 can be constructed as an integral part of the tuner housing 510. The hook 240 extends in a second longitudinal direction x 2 from the strut 220 proximate the proximal edge 222 of the strut 220 and defines a concavity 249 open towards the distal edge 221 of the strut 220 (i.e., accessible in a first transverse direction z 1 ). The hook 240 is preferably laterally elongated so as to provide at least two laterally spaced points of contact between the hook 240 and a guitar body 401 when the holder 210 is suspended from the sound hole 402 of the guitar 400 so as to increase the lateral direction y stability of the suspended holder 210. The hook 240 preferably has a lateral width of 2 to 5 cm and a longitudinal depth of 1 to 2 cm. The longitudinal depth of the concavity 249 defined by the hook 240 is preferably greater than the thickness of a standard guitar body 401 at the sound hole 402 in order to simplify hooking of the holder 210 onto a guitar body 401 and prevent the exertion of any clamping force upon a guitar body 401 by the hook 240 which could result in damage to the surface finish of the guitar body 401. Due to the oversized nature of the concavity 249, the holder 210 will tend to "lean" forward from a guitar body 401 when the holder 100 is suspended from the sound hole 402 of the guitar 400, causing a tuner 500, retained within the holding channel 239 of the connection element 230 in the tuning position to extend at a slight downward angle relative to a guitar body 401 (i.e., the front face 511 of a tuner 500 retained within the holding channel 239 in the tuning position forms an angle of slightly more than 90° (e.g., between about 100° to 120°) with the face (unnumbered) of the guitar body 401). In order to return this angle closer to 90°, the holder 210 preferably includes a protuberance 250 which extends in the second longitudinal direction x 2 from proximate the distal edge 221 of the strut 220. In a prefened aspect, the protuberance 150 extends a distance in the second longitudinal direction x 2 sufficient for causing a tuner 500, retained within the holding channel 239 of the connection element 230 in the tuning position, to extend at a slight upward angle relative to a guitar body 401 (i.e., the front face 511 of a tuner 500, retained within the holding channel 239 in the tuning position, forms an angle of slightly less than 90° (e.g., between about 70° to 80°) with the face (unnumbered) of the guitar body 401). ). By causing the front face 511 of a tuner 500 retained within the holding channel 239 of the connection element 230 to extend at a slight upward angle from the guitar body 401 when in the tuning position, the transducer 501, typically a microphone, and transducer sound opening 519 in tuner 500 will more directly face the guitar strings 410a-f and sound hole 402 of the guitar 400 and thereby improve the reception of sound emanating from the guitar 400 by the transducer 501, while also causing the visual tuning display 502 on the tuner 500 to more directly face the person (not shown) holding and tuning the guitar 400 and thereby facilitate viewing of the visual tuning display 502 during tuning of the guitar 400.. The holder 210 preferably includes a protuberance 250 which extends in the second longitudinal direction x 2 from the strut 220 proximate the distal edge 221 of the strut 220 for causing a tuner 500, retained within the holding channel 239 of the connection element 230 in the tuning position, to extend at a slight upward angle relative to a guitar body 401 when the holder 210 is suspended from the sound hole 402 of the guitar 400 (le., the front face 511 of a tuner 500 retained within the holding channel 239 in the tuning position forms an angle of slightly less than 90° (e.g., between about 70° to 80°) with the face (unnumbered) of the guitar body 401). By causing the front face 511 of a tuner 500 retained within the holding channel 239 of the connection element 230 to extend at a slight upward angle from the guitar body 401 when in the tuning position, the fransducer 501, typically a microphone, and fransducer sound opening 519 in tuner 500 will more directly face the guitar strings 410a-f and sound hole 402 of the guitar 400 and thereby improve the reception of sound emanating from the guitar 400 by the transducer 501, while also causing the visual tuning display 502 on " the tuner 500 to more directly face the person (not shown) holding and tuning the guitar 400 and thereby facilitate viewing of the visual tuning display 502 during tuning of the guitar 400. The protuberance 250 may be a single bump centered laterally on the strut 220, a pair of laterally spaced bumps, a plurality of laterally and transversely spaced bumps, a laterally elongated ridge, or any number of other structures effective for achieving the desired angling of a tuner 500 retained within the holding channel 239 of the connection element 230 in the tuning orientation. The protuberance 250 preferably has a longitudinal depth of 0.3 to 1 cm. As shown in Figures 39 and 40, a layer of protective padding 260 is preferably placed over those portions of the holder 210 which contact a guitar body 401 when the holder 210 is suspended from a guitar body 401 proximate the sound hole 402 in the guitar 400. The desired protection can generally be achieved by providing a layer of protective padding 260 over at least a portion of the second major surface 224 of the central wall 220c of the strut 220, at least a portion of the interior major surface 244 of the hook 240, and at least a portion of any protuberance 250 including at least the apex (unnumbered) of the protuberance 250. In order to maximize protection afforded by the protective padding 260, it is generally desired to provide a layer of protective padding 260 over the entire second major surface 224 of the cenfral wall 220c of the strut 220, the entire exterior surface (unnumbered) of the connection element 230, the entire interior major surface 244 of the hook 240, and the entire exposed surface area of any protuberance 250. Materials suitable for use as protective padding 260 include any material effective for protecting the surface finish of a guitar body 401 from scuffmarks, abrasions and scratches include specifically, but not exclusively, felt, foamed thermoplastics, low durometer rubber and foamed rubber, etc. Selection of a suitable material for use as protective padding 260 is well within the competency of those having ordinary skill in the art. The strut 220, hook 240 and protuberance 250 may be constructed from the same or different materials. The strut 220, hook 240 and protuberance 250, or various combinations thereof, are preferably integrally formed from a single mass of material as a single unitary article. Materials from which the strut 220, hook 240 and protuberance 250, as well as the connection element 230, may be constructed include any material having the necessary structural integrity including specifically, but not exclusively: metals such as aluminum and steel; paper products such as cardboard and cardstock; plastics such as polyethylene and polyurethane; natural and synthetic rubbers; and wood. Selection of a suitable material is well within the competency of those having ordinary skill in the art. As shown in Figures 34 and 41, a fransducer 290, such as a microphone or piezoelectric sensor, may be permanently or releasably attached to the holder 210. An electrical contact 291 is electrically connected to the fransducer 290 via electrical leads 292. The electrical contact 291 is configured and ananged to engage an electrical contact (not shown) on a tuner 500 retained by the connection element 230. The electrical contact 291 on the holder 210 can be configured and ananged relative to the electrical contact (not shown) on the tuner 500 such that engagement of the contacts is effected automatically upon engagement of the tuner 500 to the connection element 230. Alternatively, the electrical contact 291 on the holder 210 can be configured and ananged relative to the electrical contact (not shown) on the tuner 500 such that engagement of the contacts requires manual manipulation of one or both of the electrical contacts after the tuner 500 is engaged by the connection element 230 (i. e. , insertion of a male plug (not shown) at the end of an insulated electrical cord (unnumbered) extending from the holder 210 into a female input port (not shown) in the tuner 500. The fransducer 290 can be positioned substantially anywhere on the holder 210, with a preference for the interior (unnumbered) of the connection element 230. The fransducer 290 is effective for sensing any vibration generated by the playing of a guitar string 410a-f and converting the sensed vibration to an electrical signal having a value representative of the frequency of the sensed vibration. The electrical signal generated by the fransducer 290 is transmitted to the tuner 500 through the electrical leads 292 and electrical contact 291. The tuner 500 is able to utilize the electrical signal received from the transducer 290 to generate a perceptible signal (i.e., a value on a visually perceptible pitch meter) indicating any difference between the frequency of the sensed vibration and a target frequency on a standard musical scale. Fourth Embodiment Referring generally to Figures 45-58, a fourth embodiment of the invention is an assembly (unnumbered) which includes (i) a guitar tuner 300 having a fransducer 301 (e.g., a microphone) and a visual tuning display 302 retained within a housing 310, and (ii) a hook 340 extending from the housing 310. 1 The housing 310 has longitudinally spaced front 311 and back 312 walls, transversely spaced top 313 and bottom 314 walls, and laterally spaced a right 315 and left 316 sidewalls. The housing 310 may have substantially any size and shape so long as the housing 310 is large enough to retain those electronic components (not shown) necessary for proper functioning of the tuner 300 and small enough to facilitate use, transportation and storage of the tuner 300. Generally, a housing 310 having a transverse height of 4 to 12 cm, a lateral width of 3 to 12 cm, and a longitudinal depth of 1 to 4 cm accommodates these basic requirements. More preferably, the housing 310 has a fransverse height of 6 to 10 cm, a lateral width of 4 to 6 cm, and a longitudinal depth of 2 to 3 cm. When the transducer 301 of the tuner 300 is selected to sense acoustic vibrations or waves, the fransducer 301 is aligned with a sound opening 319 through the housing 310 for receiving acoustic signals from a guitar 400. The sound opening 319 may be positioned substantially anywhere on the housing 310, but is preferably placed through the front wall 311. The hook 340 extends in a second longitudinal direction x 2 from the housing 310 and defines a concavity 349 open towards the bottom wall 314 of the housing 310 (i.e., accessible in the first transverse direction z 1 ). The hook 340 preferably extends from the back wall 312 of the housing 310 proximate the top wall 313 of the housing 310, and most preferably transversely extends a distance above the top wall 313 of the housing 310 in the first transverse direction z 1 . The hook 340 is preferably laterally elongated so as to provide at least two laterally spaced points of contact (unnumbered) between the hook 340 and the guitar body 401 when the tuner 300 is suspended from the sound hole 402 of the guitar 400 so as to increase the lateral direction y stability of the suspended tuner 300. The hook 340 preferably has a lateral width of 2 to 5 cm and a longitudinal depth of 1 to 2 cm. As shown in Figures 53 through 55, the hook 340 may be slidably connected to the housing 310 for longitudinally sliding between at least a storage position, shown in Figure 54, and a tuning position, shown in Figure 54. In the storage position, shown in Figure 55, the hook 340 is drawn toward the housing 310 such that the concavity 349 defined by the hook 340 is not reasonably accessible. In the tuning position, the hook 340 is extended from the housing 310 so as to permit access to the concavity 349 defined by the hook 340 in a first fransverse direction z 1 and thereby allow hooking of the tuner 300 onto a guitar body 401 proximate the sound hole 402. As shown in Figures 56 through 58, the hook 340 may be pivotally connected to the housing 310 for pivoting about a lateral axis (not shown) between at least a storage position shown in Figure 58, and a tuning position, shown in Figure 57. In the storage position, the hook 340 is drawn toward the housing 310 such that the concavity 349 defined by the hook 340 is not reasonably accessible. In the tuning position, the hook 340 is extended from the housing 310 so as to permit hooking of the tuner 300 onto a guitar body 401 proximate the sound hole 402. The assembly (unnumbered) may optionally include a transversely extending strut 320 interposed between the housing 310 and the hook 340 with a distal edge 321 of the strut 320 attached to the housing 310 and a proximal edge 322 of the strut 320 attached to the hook 340. The strut 320 is effective for transversely spacing the tuner 300 from the hook 340 and thereby transversely spacing the tuner 300 from the guitar strings 410a-f of a guitar when the tuner 300 is suspended from the sound hole 402 of a guitar 400 by the hook 340. The strut 320 may be sized, shaped and configured as desired so long as the strut 320 extends in a fransverse direction z, is capable of securely suspending the tuner 300 from the sound hole 402 of a guitar 400, and capable of withstanding normal wear and tear. Acceptable configurations include specifically but not exclusively, a rectangular plane, a triangular plane, an ornamentally shaped plane, a framework of stiles and rails, an ornamental framework, a single central beam, a Y-shaped split beam, etc. The strut 320 preferably has a fransverse height of 1 to 5 cm and a lateral width of 1 to 10 cm. In a prefened embodiment, the strut 320 defines a first major surface 323 facing a first longitudinal direction x 1 and a second major surface 324 facing a second longitudinal direction x 2 . The longitudinal depth of the concavity 349 defined by the hook 340 is preferably greater than the thickness of a standard guitar body 401 at the sound hole 402 in order to simplify hooking of the assembly (unnumbered) onto a guitar body 401 and prevent the exertion of any clamping force upon a guitar body 401 by the hook 340 which could result in damage to the surface finish of the guitar body 401. Due to the oversized nature of the concavity 349, the tuner 300 will tend to "lean" forward from a guitar body 401 when the assembly (unnumbered) is suspended from the sound hole 402 of the guitar 400, causing the bottom wall 314 of the tuner housing 310 to extend at a slight downward angle relative to a guitar body 401 (i.e., the bottom wall 314 of the housing 310 forms an angle of slightly more than 90° (e.g. , between about 100° to 120°) with the face (unnumbered) of the guitar body 401). In order to return this angle closer to 90°, the assembly (unnumbered) preferably includes a protuberance 350 which extends in the second longitudinal direction x 2 from proximate the bottom wall 314 of the housing 310. In a prefened aspect, the protuberance 350 extends a distance in the second longitudinal direction x 2 sufficient for causing the bottom wall 314 of the housing 310 to extend at a slight upward angle relative to a guitar body 401 when the assembly (unnumbered) is suspended from the sound hole 402 of the guitar 400 (i.e., the bottom wall 314 of the housing 310 forms an angle of slightly less than 90° (e.g., between about 70° to 80°) with the face (unnumbered) of the guitar body 401). By causing the bottom wall 314 of the housing 310 to extend at a slight upward angle from the guitar body 401, the fransducer 301, typically a microphone, and fransducer sound opening 319 in the tuner 300 will more directly face the guitar strings 410a-f and sound hole 402 of the guitar 400 and thereby improve the reception of sound emanating from the guitar 400 by the transducer 301, while also causing the visual tuning display 302 on the tuner 300 to more directly face the person (not shown) holding and tuning the guitar 400 and thereby facilitate viewing of the visual tuning display 302 during tuning of the guitar 400. The protuberance 350 may be a single bump centered laterally on the housing 310, a pair of laterally spaced bumps, a plurality of laterally and transversely spaced bumps, a laterally elongated ridge, or any number of other structures effective for achieving the desired angling of the tuner 300. The protuberance 50 preferably has a longitudinal depth of 0.3 to 1 cm. As shown in Figures 45, 50, 51 and 52, a layer of protective padding 360 is preferably placed over those portions of the tuner 300 which contact a guitar body 401 when the tuner 300 is suspended from a guitar body 401 proximate the sound hole 402 in the guitar 400. The desired protection can generally be achieved by providing a layer of protective padding 360 over at least a portion of the exterior major surface 312e of the back wall 312 of the housing 310, at least a portion of the interior major surface 344 of the hook 340, and at least a portion of any protuberance 350 including at least the apex (unnumbered) of the protuberance 350. In order to maximize protection afforded by the protective padding 360, it is generally desired to provide a layer of protective padding 360 over the entire exterior major surface 312e of the back wall 312 of the housing 310, the entire exterior major surface 314e of the bottom wall 314 of the housing 310, the entire interior major surface 344 of the hook 340, and the entire exposed surface area of any protuberance 350. Materials suitable for use as protective padding 360 include any material effective for protecting the surface finish of a guitar body 401 from scuffmarks, abrasions and scratches include specifically, but not exclusively, felt, foamed thermoplastics, low durometer rubber and foamed rubber, etc. Selection of a suitable material for use as protective padding 360 is well within the competency of those having ordinary skill in the art. The housing 310, hook 340 and protuberance 350 may be constructed from the same or different materials. At least a portion of the housing 310, the hook 340 and the protuberance 350, or various combinations thereof, are preferably integrally formed from a single mass of material as a single unitary article. Materials from which the housing 310, hook 340 and protuberance 350 may be constructed include any material having the necessary structural integrity including specifically, but not exclusively: metals such as aluminum and steel; paper products such as cardboard and cardstock; plastics such as polyethylene and polyurethane; natural and synthetic rubbers; and wood. Selection of a suitable material is well within the competency of those having ordinary skill in the art. As shown in Figure 52 a transducer 301, such as a microphone or piezoelectric sensor, is provided within the housing 310. The fransducer 301 is effective for sensing the vibration generated by the playing of a guitar string 410a-f, and converting the sensed vibration to an electrical signal having a value representative of the frequency of the sensed vibration. The tuner 300 includes the necessary hardware, software and/or firmware (not shown) to generate a perceptible signal (i. e. , a value on a visually perceptible pitch meter) indicating any difference between the frequency of the sensed vibration and a target frequency on a standard musical scale.
