Abstract

The invention relates to a device intended to facilitate play on a musical string instrument by transfer of the notes for a tune to be played from the conventional note sheet onto a note sheet where the tones are indicated so as they are to be found at predetermined places on the individual strings of the instrument by the fingers of the hand acting on the strings. The device consists mainly of a preferably rectangular, flat, elongated slotted slider and a preferably rectangular, flat, elongated slide member housed in the slot so as to allow mutual sliding displacement. The slide member is provided with longitudinally extending parallel rows of conventional tone designations by characters, the number of said rows equalling the number of the strings of the instrument. The tone designating characters are in each row positioned according to their subsequent locations on the string. The slide member is formed with one or several apertures disposed according to a specific pattern so as to be capable of uncovering groups of tone designations belonging to either the same key or the same chord. The opposite side of the slider and slide member device may be formed with tone designations on the slide and apertures in the slider grouped so as in predeterminable setting positions relative one another to lay open the chords and keys belonging to the specific keytone of each of the strings of the instrument. By means of this device a note sheet can be prepared which renders possible immediately to read off the positions of each finger of the hand acting on the individual strings for producing the tune in consideration. This novel note sheet has groups of parallel horizontal lines the number of which equals the number of the strings of the instrument and the notes are marked on the lines only, with an adjacent annotation of the number of the finger to be pressed against the string at the location indicated by the position of the note, the general location of the hand with its four fingers relative the strings of the instrument being determined by a separate illustration beside the groups of lines. The desired tune can be played from the novel note sheet by a player with the normal training for playing the instrument in consideration.

Claims

1. A guide for a musical string instrument of the type having a fingerboard and frets for producing tones, and which directly indicates where the fingers of the hand are to be located along the individual strings of the instrument so that various tones shall be produced, comprising

a slotted slider, and

an elongate slide member movably housed in said slider, said slider and said slide member being slidably displaceable relative to one another in a direction extending longitudinally of said slide member,

said slide member being provided with mutually parallel, longitudinally extending rows of pairs of conventional tone denoting characters, the number of said rows equalling the number of strings of the instrument, and successive pairs of characters in each of said rows being placed according to corresponding successive tone positions on a corresponding one of said strings,

the slider having on one side thereof a plurality of spaced parallel fret denoting lines at least one series of openings devised selectively to register with and selectively to display, groups of characters, each of which groups is selected from among a predetermined plurality of successive pairs of said characters in each row thereof,

the characters in each of said rows representing all tones, including full tones and half tones playable by the associated string, beginning from the key tone of said associated string and rising in scale over at least one octave, and each of said full tones and half tones in each octave being represented twice in immediate sequence on said slide member by one of said pairs of characters, and

said series of openings being disposed in said slider in such manner that each group of characters displayed thereby incudes at least one basic key tone and all of the additional tones and half tones required to denote the scale for at least two octaves in said basic key tone.

2. The guide as claimed in claim 1 wherein said openings are arranged so that the characters of each of said groups of tone denoting characters are selected from among four successive pairs of said tone denoting characters in each row thereof.

3. The guide as claimed in claim 1, wherein said openings are arranged so that the groups of selected tone denoting characters consist either of the characters which form the first of the two characters in each pair thereof, or the second of said two characters of each pair.

4. The guide as claimed in claim 1, characterized in that the instrument is a guitar and the number of rows is six.

5. The guide as claimed in claim 1, wherein at least one field is arranged on the slider and comprises four rows corresponding to the number of fingers disposed to be used on the strings of the instrument, and extending transverse to the direction of said rows of tone denoting characters, and

said openings are formed in said slider in such a manner as to have each opening register with one of said transverse rows on said slider and with one of said underlying rows of characters on said slide member thereby to display the registering tone denoting characters on the slide member in the sequence typical for the scale in the said basic key tone.

6. The guide as claimed in claim 1, wherein at least one of said openings in said series is marked in a manner distinguishing said one opening from the other openings in said slider.

7. The guide as claimed in claim 1, wherein

said rows of characters are formed on each side of said slide member, and

said slider has therein, in the side opposite that containing said one series of openings, a second series of openings disposed to register with and display characters which define chords in both key major and minor.
