Universal musical scale, scale pattern, and chord indicator

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.
