Murdock - Web page: https://patentgrep.com/patent/US7408105B2 ## CPC - G10G 1/02: Chord or note indicators, fixed or adjustable, for keyboard of fingerboards - G10G: REPRESENTATION OF MUSIC; RECORDING MUSIC IN NOTATION FORM; ACCESSORIES FOR MUSIC OR MUSICAL INSTRUMENTS NOT OTHERWISE PROVIDED FOR, e.g. SUPPORTS (music stands A47B; non-musical aspects of musical toy instruments A63H5/00; metronomes G04F5/02; teaching music G09B15/00) ## Abstract An instrument training device for use with a stringed instrument includes a plurality of training members. Each training member is constructed of a flexible material and includes opposed ends. Each end includes complementary fastening material such as hook and loop fasteners for securing a respective training member about a fret board of a stringed instrument by releasably fastening the opposed ends together. Each training member includes indicia on a front portion thereof corresponding to chord sets or tuning schemes. The front portion is constructed of a resilient or elastic material that may be stretched across the front surface of the fret board such that the indicia thereon is situated directly beneath predetermined strings. This enables each training member to be used on stringed instruments of different sizes or widths. Each training member includes an identifier for positioning the training member at a predetermined position along a fret board. ## Claims ### Claim 1 An instrument training device for use with a stringed instrument having a fretboard and at least one string, said training device comprising a plurality of training members, each said training member comprising: first and second opposed ends which may be selectively secured together; a face portion situated between said first and second ends, said face portion having indicia for conveying predetermined information, said face portion having elastic properties to allow said face portion to be extended across the fretboard; wherein at least one said training member includes first and second positioning elements; and wherein said first and second positioning includes configurations that are complementary to corresponding opposed sides of the fretboard so as to maintain said face portion at a predetermined position in respect to the fretboard; and wherein each said training member includes an identifier so that said training members may be positioned at predetermined locations alone the fretboard. ### Claim 2 (depends on 1) The training device as in claim 1, wherein: said first end includes at least one of a hook fastener and a loop fastener; and said second end includes at least another of said hook fastener and said loop fastener. ### Claim 3 (depends on 1) The training device as in claim 1, wherein said indicia includes at least one of letters, numbers, and colors. ### Claim 4 (depends on 1) The training device as in claim 1, wherein said indicia includes alphabetic data indicative of musical notation. ### Claim 5 (depends on 4) The training device as in claim 4, wherein said indicia includes color indicative of a predetermined tuning scheme. ### Claim 6 (depends on 4) The training device as in claim 4, wherein said indicia includes color representative of a predetermined chord group. ### Claim 7 (depends on 1) The training device as in claim 1, wherein said face portion is sized to fit between the fretboard and the at least one string. ### Claim 8 (depends on 7) The training device as in claim 7, wherein at least one of said first and second ends is sized to pass between the fretboard and the at least one string. ### Claim 9 (depends on 1) The training device as in claim 1, wherein said indicia is formed by color-coded dye injected into said face portion. ### Claim 10 (depends on 1) The training device as in claim 1, wherein at least one said training member includes indicia that is different from said indicia of another said training member. ### Claim 11 (depends on 1) The training device as in claim 1, wherein said face portion is constructed from at least one material selected from the group consisting of rubber and latex. ### Claim 12 (depends on 1) The training device as in claim 1, wherein said face portion has a height that is less than a height of a fret on the fretboard. ### Claim 13 A training member for use with any of a plurality of stringed instruments having a fretboard and at least one string, said training member comprising: first and second opposed ends, said first and second ends having cooperable securing elements; a face portion between said first and second ends, said face portion having indicia to convey predetermined information, said face portion having elastic properties to allow said face portion to be extended across each respective fretboard; a said indicia includes alphabetic data representative of musical notation; said indicia color representative of a predetermined tuning scheme or a predetermined chord group; said cooperable securing elements include hook and loop fasteners; said face portion is size to fit between the fretboard and the at least one to string; and first and second positioning elements are in communication with said face portion and configured to correspond to opposed sides of each respective fretboard to maintain said face portion at a predetermined position in respect to each respective fretboard. ### Claim 14 (depends on 13) The training member as in claim 13, wherein: said indicia includes alphabetic data representative of musical notation; and said indicia includes color representative of a predetermined tuning scheme or a predetermined chord group. ### Claim 15 (depends on 13) The training member as in claim 13, wherein: said face portion is sized to fit between the fretboard and the at least one string; and at least one of said first and second ends is sized to pass between the fretboard and the at least one string. ### Claim 16 (depends on 13) The training member as in claim 13, wherein: said cooperable securing elements include hook and loop fasteners; and said indicia is defined by color-coded dye injected into said face portion.
