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.
A universal musical scale, scale pattern, and chord indicator for use in teaching a preselected musical scale and for simplifying the task of locating a multiplicity of ascending and descending points for learning finger positioning of the scale as it relates in a series of pattern voicings to a fingerboard of a fretted musical instrument, comprising: (a) an improved slide rule type device including a housing having an aperture and a series of at least eight display windows thereon, at least seven said display windows of which further having indicia indicative of a scale degree respectively printed correlatively adjacent thereto, and further including a transparency positioned within one of said display windows, said transparency having indicia printed thereon to simulate said fingerboard, and further having an imprinted series of position alignment indicia and an imprinted index of tone letters, (b) a displaceable medial sliding member having an aggregate of color coded dots thereon, said aggregate including an imprinted index of finger position indicia wherein a number of said dots are characteristically divided into two contrasting colors and are arranged and printed on said member in a predetermined manner by which insertion of said member into said aperture of said housing and through which discretionary alignment causes the two contracting colors of each of said dots to correspond with respective said tone letters of said transparency whereby indicating single fingering positions contained within two opposed said pattern voicings and further enabling simultaneous correspondence to said multiplicity by way of said aggregate, and (c) an imprinted series of both straight and curved interconnecting lines located on said housing which serves to isolate at least three of said display windows, and said member further having an imprinted system of at least four tone indicators thereon which individually consist of a series of laterally spaced letter delineations for musical tones, each of which is arranged and printed in a predetermined manner by which said insertion of said member into said aperture of said housing and through which said discretionary alignment further causes correspondence of each of said tone indicators respectively with at least one of said display windows, said tone indicators thereby maintaining a definite relationship with said imprinted series whereby effecting simultaneous indications in reference to tonality.
