## Background
BACKGROUND OF THE INVENTION
Field of the Invention
A guitar fingering aid that is arranged for adjustable mounting to the fingers of a musician with a device thereof for fitting around their middle finger and is supported by at least one of the musician's two adjacent fingers that rest on finger support or supports, and which guitar fingering aid includes one or more small finger bars for adjustable installation onto a guitarist's small finger, where the fingering aid is used to engage the neck of a stringed instrument, such as a guitar, ukulele, banjo, or the like, and to assist to a musician who has difficulty in depressing some or all the instruments strings with their fingers in a normal manner to play the instrument, where such person is impaired or suffers from arthritis, and which fingering aid can be used as a teaching aid for a student learning to play the instrument.
Prior Art
The invention in a guitar fingering aid device is for fitting onto a musician's middle finger and includes a small finger bar that are for assisting a musician who, because of a physical impairment, such as arthritis, finds reaching and pressing the instrument strings with their fingers to be difficult, and is useful for a assisting a person who wishes to learn to play a guitar, or like instrument, who may not have sufficient finger dexterity to correctly and comfortably place their fingers on the instrument strings, or is unable to reach, and or, exert sufficient pressure on, the instrument strings through their fingers to produce a desired sound from the instrument. For such persons, use of the fingering aid allows a musician to continue playing a stringed instrument when they are, or are becoming, physically impaired, and, further, the guitar fingering aid can be used to assist a novice in developing their instrument playing skills.
Where other earlier fingering aid devices have promised to afford a musician, who is experiencing a progressive impairment, such as arthritis, with a capability to play a stringed instrument, such as a guitar, or the like, such have not allowed the musician to play the four predominant chord groups, including all major, minor, seventh and minor seventh chords in a flowing manner, using all the instrument strings, as does the guitar fingering aid of the invention. Such limitations deprive the experienced musician with an ability to play all of the four predominant chord groups that are often required in a composition of most folk, country, pop, bluegrass, religious hymns and traditional songs. Also, the guitar fingering aid of the invention allows the musician to strum or pick all of the instrument strings simultaneously, and allows the musician to utilize their usual playing style, without a need to interrupt the flow of the music. Additionally, while playing not only the four predominant chord groups, it allows for a playing of an additional four common chord groups that include: all sixth, minor sixth, major seventh and minor/major seventh chord groups. Whereas, such uninterrupted play is not possible with earlier devices that often require a changing of such earlier device, as by adjusting positioning of such earlier device, in the body of the song. The guitar fingering aid of the invention allows for the utilization of standard musical principles and does not require that the experienced player relearn a new chording system as earlier devices do.
For the novice musician, the use of the guitar fingering aid of the invention encourages them to develop guitar playing skills that do not require a struggle with chord formation and sore fingers, allowing them to concentration on learning picking and strumming styles before learning to play a guitar in the traditional way. A method for use of the guitar fingering aid allows the use of normal standard musical principles and does not confuse the novice player with non-transferrable methods, as do earlier devices, should they move on to traditional playing method, and does not require an experienced player to relearn an unnecessary system.

Still another object of the present invention is to provide a device having a main bar with a rounded length and is slightly curved along its undersurface such that, when the device is rolled, pivoted, or tilted, the musician, by moving their hand appropriately, can move the main bar under surface into contact selected instrument strings such that the musician, by strumming or picking the instrument strings, can play a selected musical selection.
Still another object of the present invention is to provide a guitar fingering aid that includes the device that is arranged to be easily adjustably fitted onto a finger of a the musician's hand that holds the instrument neck, and includes a finger support or supports arranged for mounting at one or more spaced holes formed through the device main bar web, to project at right angles out from one or opposite sides of the main bar web, and which finger support or supports can be aligned or spaced apart, to avoid a painful arthritic joint, or joints, and receive the undersurface of at least one of the musician's fingers for aiding movement in conformity with movement of the musician's hand while allowing the ends of the fingers to themselves engage selected string of the instrument, with the finger support or supports to also contact selected instrument strings during play, allowing a handicapped musician or novice musician to comfortably play the instrument.
Still another object of the present invention is to provide a device that allows the ends of the fingers of the hand whereto the device is mounted to themselves to engage the instrument strings, and the guitar fingering aid, in addition to the device for mounting to the musician's finger of their hand that grips an instrument neck, includes at least one small finger bar arranged for releasable mounting by straps onto the small finger of the musician's hand that engages the neck of a stringed instrument, such as a guitar, ukulele and banjo, with the combination of the device and small finger bar mounted to the musician's hand to allow a handicapped or novice musician to correctly sequently depress selected strings of the instrument, and apply adequate pressure on which selected strings by moving it along the neck and rolling, pivoting and tilting the device using essentially the same movements of their hand as the musician would have employed before they became impaired.
Still another object of the invention in a guitar fingering aid is to provide a device and small finger bar that allow an accomplished musician to continue playing a guitar, or other string instrument, such as a ukulele or banjo, with the aid of the guitar fingering aid, at a like skill level as they had before they became impaired as by an onset of a debilitating disease, such as osteoarthritis or rheumatoid arthritis, resulting in musician's finger movement becoming painful and difficult, greatly limiting the joy and happiness as they had experienced in playing their instrument. Also, a musician who, through accident, has lost a finger, or use of a finger or fingers, to continue playing their instrument. Also, for a beginning or novice player, use of the invention allows the player to concentrate on learning rather than struggling with chord formations and sore fingers, before choosing to play the guitar utilizing conventional techniques.
The guitar fingering aid of the invention principal features include a device and small finger bar for mounting onto a musician's hand that holds a guitar type instrument neck that are for operation together to facilitate a musician playing a musical composition, allowing that musician to continue to play a guitar, or like string instrument, after they become handicapped or disabled in the manner as they did before they became handicapped or disabled, which guitar fingering aid device and small finger bar can be easily set up with component parts thereof connected together for various instrument open tunings to provide the musician with a capability to play a number of musical selections without changing the device configuration.
Preferably, the guitar fingering aid device and small finger bar are formed from a somewhat flexible material, such as soft vinyl or nylon material, to both support and cushion the musician's fingers and to contact the instrument strings in a fashion that is similar to the musicians usual finger end pressure as they formerly applied through their fingers onto the individual instrument strings.
The invention is in the guitar fingering aid that includes a device and a small finger bar, with the device arranged for mounting onto a musician's finger and includes a main bar that has an instrument string engaging under surface that extends across the web from a palm engaging post to the end of the main bar. Which string engaging surface has a uniform convex curve formed along its length and is concave between the palm engaging post and main bar end, and which palm engaging upper end, and the main bar has flat parallel web sides. Holes are formed at equal spaced intervals through the web sides that individually receive a fastener or fasteners to mount individual finger supports or an outrigger bar to extend outward from which web sides, with at least one of the finger supports is supported by a finger of the musician that is adjacent to their finger that mounts the device. Whereby, when the device is slid along a guitar neck, and is tilted, rolled, pivoted and moved vertically by the musician's hand that mounts the device such that, with the musician's hand guiding the contact with selected strings along the web undersurface and, with the movement of the small finger bar to also contact selected strings, the musician can play a selected musical composition. The spaced holes formed at intervals through the device main web, are to receive a threaded rod fitted therethrough to provide for an attachment of a finger support or supports and/or an outrigger bar. Which rod or rods have threaded ends that are to receive and turn onto, a finger support or supports, and, at least one finger support is mounted onto the end of a rod that has a screw type head. Also, to provide for reuse of the finger supports and outrigger bar, they each have holes formed in ends that can receive a threaded end of the rod, or which individual hole, can receive a sleeve fitted therein that receives the rod threaded end turned therein. The finger supports and outrigger bar are for fitting through selected holes formed through the main bar web to form right angles thereto, and can be aligned, or can be off-set from one another, depending upon the set up configuration of the device. Where the finger supports are aligned, they can each be fitted onto an end of a single rod that does not include a screw type head, where the rod is fitted through one of the spaced main bar web holes. With the device mounted onto the musicians' finger, the finger support or supports undersurface support the finger or fingers of the musician hand that are adjacent to the finger that mounts the device. So arranged, the device is mounted to allow the main bar to be rolled, pivoted, and tilted, as it is moved by the musician's hand up and down the instrument neck, contacting selected points along the instrument strings for the musical composition being played.
The finger supports and outrigger bar can be cylindrical, or have flat or rounded sides and can each be easily released from the rod and screw ends, allowing for the assembly of the finger supports to appropriate positions along the device web for a particular instrument open tuning for playing a selected musical selection. Whereafter, the finger supports and outrigger bar can be easily repositioned appropriately, for the same or another instrument open tuning, to the main bar web to play another musical selection.
The guitar fingering aid and small finger bar or bars are arranged to be easily adjustable, as with straps, to the musician's middle and small fingers, and includes outer surfaces that engage selected instrument strings during instrument playing.

With the device 10 and small finger bar 11 mounted to the hand 40, the musician, by sliding their hand up and down the instrument neck and tilting, rotating and pivoting their hand appropriately can sequentially engage selected strings 1 through 6 to play the chords of a musical composition. With the device 10 configured, or set up, as shown in FIGS. 1, 1A, 2, 3 and 3A, and with the small finger bar 11 mounted onto the musician's small finger, as shown in FIGS. 1, 1A and 2, the musician can play a number of musical selections without a reconfiguration of the device 10.
Specifically, in a practice of the method of the invention for playing a musical composition, with the device 10 set up as shown in FIGS. 1, 1A and 2, and with the guitar tuned to open Dm7, as shown in FIGS. 12 through 12H, and which tuning can also be tuned to open Cm7 and Em7, within the scope of this disclosure, the musician can form all Major, Seventh, Minor, Minor Seventh, Sixth, Minor Sixth, Major Seventh, and Minor/Major Seventh Chords, by using a combination of, pressing selected strings to form the chords, while both lifting and lowering of the small finger bar 11, onto strings 1 and 2, as shown in FIGS. 5 through 5C, and pivoting, rolling, and tilting the device 10 to engage the strings 1 through 6, as they move their hand up and down the instrument neck 9. Which positioning of the device 10 and small finger bar 11 is illustrated in FIGS. 12A through 12H, that show the string contacts points as black dots positioned over the respective strings as are contacted during playing of the selected chords to play a musical composition, allowing the musician to form all ninety six (96) of the most commonly used chords. Further, additional to the device 10 basic set up of FIGS. 1, 1A, 2, 3 and 3A, other components of the device 10 can to added to the device 10 basic set up to include, as shown in FIGS. 8 and 8A, the second finger support 22b, and may include the second small finger bar 60, as shown in FIG. 8B as well as additional finger supports 22c along with an outrigger bar 23, as shown in FIG. 9 Where, in such set ups, the finger supports 22a and 22b along with the outrigger bar 23 are mounted to different holes alongside one another through the main bar web 13 sides 13a and 13b, extending outwardly, at right angles, therefrom. As shown, in FIG. 8B, the small finger bar 11 is fitted to the musician's small finger, as shown mounted in FIGS. 1, 1A and 2, and further includes the small finger bar 60 fitted onto the musician's small finger above their knuckle. With the different device set ups here set out, and with the guitar tuned to one of the selected open tunings, as discussed above, one hundred thirty two (132) additional chords can be played with device 10 and small finger bar 11, set up as shown in FIGS. 8B and 9,
As set out above, the device 10 can employ a variety of configurations thereof and, along with the small finger bar 11, constitutes the guitar fingering aid 8. Further, the aid can also include, as appropriate, an additional or second finger bar 60, and additional finger supports and one or more outrigger bars 23. The combination of which guitar fingering aid 8 device 10, and small finger bar 11, of FIGS. 1, 1A, 2, 3 and 3A, however, constitutes the basic configuration of the guitar fingering aid 8 of the invention and is for use by a handicapped musician who has lost or damaged a finger or finger, and, additionally, is suitable for use by a novice student who has sensitive finger tips and is discouraged from play by the discomfort associated the redundant depression of the instruments strings, which discomfort can be avoid with a use of the guitar fingering aid.
In practice, the device 10 and small finger bar 11 and second small finger bar 60 are preferably manufactured from a soft moldable material, such as a flexible vinyl or thermoplastic elastomer that will, when pressed onto a string, provide a flow such that, when it is pressed on a string, the soft malleable material tends to flow across and slightly down the string, mimicking the musician's fingers pressing on an instrument string. Also, for the handicapped musician, they often cannot comfortably reach out their fingers, or bend them appropriately to reach and properly press the instrument strings during normal play.
