MELODY CHORD CONSTRUCTOR FOR STRING INSTRUMENTS

摘要

After a brief discussion of the construction and operation of a typical stringed instrument, such as a guitar, a melody chord constructor therefor is shown which includes a base unit having located thereon symbols denoting the instrument's musical notes which are arranged in rows and columns corresponding to the fingerboard's strings and frets. A transparent member is relatively slidable on the base unit and has located thereon a plurality of numerical symbols arranged in rows and columns corresponding to those of the base unit. In one position, the symbols "1" on the slide member register with note symbols on the base unit corresponding to the root notes of an arbitrarily chosen scale, such as G. The remainder of the numerical symbols correspond to the major scale degrees useful in melody chord construction, that is, the 3, 5, 6, 7, b7, 9 and 11 degrees, and register with the corresponding notes of the G major scale on the base unit. By translating the slide member relative to the base unit, the notes corresponding to the root and degrees of any other major scale can be readily ascertained. Additional slide members having the various minor scale degrees thereon can be interchanged with the major scale slide member.
