Apparatus and method for visual and audible demonstration of musical concepts

摘要

The inventors disclose a new apparatus and method for visual and audible demonstration of musical concepts such as intervals, the tonic, transposition, scales, modes, and chords. The apparatus is based on a primary layer of indicia for each of the 12 chromatic notes of the musical octave, each indicium paired with a touch sensor. A novel means for superimposing additional layers of musical information employs a tonic indicator and encoder, and modular physical indicator pieces or multi-colored LED lights.
