ABSTRACT:
A device for demonstrating musical scales and chords in various tonics for use with a fretted stringed musical instrument. A housing is of a slide-rule nature and has a transparent simulated fingerboard positioned within a display window. This fingerboard is reticulated, with an imprinted series of uniformly-spaced parallel string lines extending longitudinally and representing the strings of the instrument. These lines are regularly interrupted by an imprinted series of position alignment indicia and tone letters. A series of uniformly-spaced printed parallel lines transverse the longitudinal lines and represent the nut and frets of the instrument. Additional display windows disclose a plurality of related information; these windows are used primarily to identify certain tonal characteristics. A plurality of displaceable medial sliding members is provided, each having a system of tone indicators printed in a predetermined manner. These indicators are used to identify tonality. A plurality of color-coding systems, also printed in a predetermined manner, consist of an index of finger position indicia. These coding systems are used to isolate a maximum of five scale patterns for every twelve frets of fingerboard travel and also to identify finger placements for chord formations. When a preselected sliding member is inserted into an aperture of the housing, these indicators and coding systems align with their respective display windows and position alignment indicia. Thus, the related tone locations are identified for each tonic selected.
