FIELD OF THE INVENTION
This invention relates generally to chord playing attachments and specifically to a specially configured chord playing attachment that may be used to play a guitar or be employed as a teaching tool, and wherein a specially configured nut arrangement enables disassembly of the chord playing portion from the nut in order to play the guitar without the chord playing portion.
BACKGROUND OF THE INVENTION
Two problems present themselves when a student attempts to learn the guitar or a similar stringed instrument. The guitar strings injure the student's fingertips until the student develops calluses; and the student faces a steep learning curve prior to playing actual music. The latter problem often causes severe frustration, which in turn causes most novices to quickly abandon their learning attempts. Teaching the student a series of musical chords allows the student to play music quickly, which encourages the student to keep playing until greater understanding is gained and reduces frustration.
Various chord attachments have been developed to allow the user to play chords easily without injuring their fingers. None of these devices have ever attained widespread popularity because none of them have been designed as teaching tools. Many of the older versions were intricate, heavy, and hard to use. Some even mask the strings from the user's view, resulting in the user being unable to learn any chords while using the device. Newer versions are more usable, but do not encourage the user to play any strings directly. This forces the user to build up calluses all at once and forces the user to make the mental leap directly from playing by pressing buttons to playing by depressing complex string combinations. None of the previous chord attachments allow the user to take an intermediate step or steps to ease them into the process of playing without the aid of training devices. Also, none of the previous chord attachments were paired with a user friendly training manual to teach the user how to play chords in the right order to create songs without requiring the user be able to read standard sheet music. Additionally, many of the previous chord attachments depress all of the guitar strings at a specific point, which causes those devices to act as a capo. A capo device is undesirable because it changes the key of all of the chords played, which means that any attempts to play the guitar with the attached device will result in music that is nonstandard.
Therefore, what is needed is a chord playing attachment. The chord playing attachment should allow the user to play some chords by hand and some chords by depressing buttons. The chord playing attachment should also be used in combination with a color-coded training manual. Furthermore, other desirable features and characteristics of the present invention will become apparent when this background of the invention is read in conjunction with the subsequent detailed description of the invention, appended claims, and the accompanying drawings.
My PCT Patent Application Serial No. PCT/US11/44002, filed 14 Jul. 2011, and published on 19 Jan. 2012 under publication no. WO 2012/009533, is hereby incorporated herein by reference.
SUMMARY OF THE INVENTION
The present invention advantageously fills the aforementioned deficiencies by providing a specially configured chord playing attachment. The chord playing attachment of the present invention includes chord members (e.g., levers) with color-coded finger pads that enable a user to depress the strings necessary to play a chord or part of a chord. The chord playing attachment is also usable in combination with a color-coded training manual for easy learning. In one embodiment, the levers and buttons are removable from a specially configured guitar “nut” so that a user can play the guitar without the chord playing portion.
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, which are intended to be read in conjunction with both this summary, the detailed description, and any preferred and/or particular embodiments specifically discussed. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of illustration only and so that this disclosure will be thorough, complete and will fully convey the full scope of the invention to those skilled in the art.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1-18 show the preferred embodiment of the apparatus of the present invention designated generally by the numeral 10. Guitar apparatus 10 provides a body 11, neck 12, head 16 and strings S. The neck 12 has a first neck side 13 and a second neck side 14. The neck 12 provides a fret board 15. The head 16 carries a plurality of tuning pegs 17 for adjusting tension of each string S. The fret board 15 has a plurality of parallel frets 18. The body 11 can provide a pick guard 19. Bridge 20 is provided on body 11. String S attach to bridge 20.
As part of the method and apparatus of the present invention, a slot 21 can be cut or milled in neck 12 next to head 16 as seen in FIG. 3. The slot 21 is receptive of a specially configured nut or connector or anchor 22.
The nut or connector or anchor 22 provides a base portion 23 having a lower surface 28 that registers against the neck 12. If a slot 21 is milled in neck 12, the base 23 rests in the slot 21. Spaced apart openings 29 can be provided in nut/connector/anchor 22 for attaching it to the neck 12 using fasteners 63 such as threaded wood screws (see FIG. 3).
Nut/connector/anchor 22 has a raised portion 30 having a plurality of string depressions 24, each receptive of a different one of the guitar string S. A pair of spaced apart side anchors or projections 25, 26 are provided. In between the side anchors or projections 25, 26 there can be provided a socket or longitudinal slot 27 (see FIG. 11). The longitudinal slot or socket 27 can provide a generally horizontal surface 31 and a generally vertical surface 32.
Nut/connector/anchor 22 has a front 33 and a rear 34. Nut/connector/anchor 22 has a first side 35 and a second side 36. Each of the side anchors or projections 25, 26 extends away from a side 35, 36 as shown in FIGS. 11-17. Preferably, first side 35 and second side 36 of nut/connector/anchor 22 are aligned with first neck side 13 and second neck side 14, respectively. When sides 35, 36 of nut/connector/anchor 22 are aligned with neck sides 13, 14, nut projections 25, 26 will extend beyond the sides of the neck 12.
A chord playing attachment 40 (see FIGS. 2-10) is removably connectable to nut/connector/anchor 22 at the side anchors or projections 25, 26. The chord playing attachment 40 provides a frame 41 that can be of plastic (e.g., transparent plastic), metal or other material. The chord playing attachment 40 has opposed sides 42, 43 that form an arch 62 with transverse section 48. Diagonally extending tabs or angled flanges 44, 45 can extend down and away from sides 42, 43 as shown in FIGS. 9, 10. Each of the sides 42, 43 provides an opening. Side 42 provides opening 46. Side 43 provides opening 47. Each of the openings 46, 47 is sized and shaped to receive and connect with a side anchor or projection 25, 26. The distance 37 between sides 35, 36 can be equal to or slightly greater than the distance 38 between sides 42, 43 of frame 41 (see FIGS. 10 and 15). In this fashion, the sides 42, 43 clamp the nut/connector/anchor 22 with a clamping or interference fit connection.
When a side anchor or projection 25 or 26 extends into an opening 46 or 47, a side 35 or 36 of nut/connector/anchor 22 abuts or engages a side 42, 43 of frame 41 as shown in FIG. 3. In order to disconnect the chord playing attachment 40 from the nut/connector/anchor 22, a user simply grasps each of the sides 42, 43 or angled flanges/diagonally extending tabs 44, 45 and moves them apart in the direction of arrows 64 in FIG. 3. The arch 62 thus flexes to disconnect frame 41 from the nut/connector/anchor 22.
A central post/leg/flange 49 can extend downwardly from transverse portion 48 at a position midway between sides 42, 43 of chord playing attachment 40. The post 49 engages and occupies the longitudinal slot or socket 27 when chord playing attachment 40 is connected to nut/anchor/connector 22 and surface 65 engages surface 31.
Frame 41 supports a plurality of levers 50, 51, 52, 53. Each of the levers or depression members 50-53 can be provided with a button 54, 55, 56 or 57. In this fashion a user can push on a button 54-57 as selected for a particular chord in order to depress a selected lever 50, 51, 52 or 53. The buttons 54-57 can be the same as described in my prior PCT Application Serial No. PCT/US11/44002, filed 14 Jul. 2011, and published on 19 Jan. 2012 under publication no. WO 2012/009533. Each of the levers 50-53 is provided with a depression member 58-61. The depression members 58, 59, 60, 61 move down and contact and depress a string (or strings) S when a user presses on a selected lever 50-53 or its button 54-57. The depression members 58 are a part of lever 50. The depression members 59 are part of the lever 51. The depression member 60 is a part of the lever 52. The depression members 61 are a part of the lever 53. Each lever 50-53 can be integrally or removably attached to frame 41 at arch 62 as seen in FIG. 5.
The attachment apparatus of the present invention can be sized for 1⁄2 size guitars, 3⁄4 size guitars, and full size guitars. The present invention includes both the attachment apparatus and the guitars to which the attachment apparatus is attached.
The present invention as shown in FIGS. 1-18 is commercially available from Peavey for 3⁄4 size guitars, and full size guitars.
The inventor also plans to market a smaller attachment apparatus for 1⁄2 size guitars similar to what is shown in FIGS. 1-18. In the prototype, the overall length is 94 mm, the width is 47 mm, and the “B” string stud was moved down the neck approximately 7 mm Optionally, the finger buttons can be built into the clear plastic mold and colored tabs (such as colored self-adhesive paper) can be added after manufacture of the clear plastic part. The main function of the present invention (to be sold by Perry's Music as ChordBuddy Jr. guitar apparatus) is to allow a student to gain the skill of strumming chords and proper timing without having to concern themselves with making the chord shapes, while building up finger dexterity and strength in the chord-making hand.
