Abstract
Abstract A tone generating oscillator selectively generates any one of the twelve tones of the musical scale upon activation of a unique combination of four keys. Other keys are provided for generating the selected note in a higher or a lower octave. Each of the tones is assigned a particular character consisting of a graphical representation of the utilization of one or more of the four keys; and, in a particular musical theme, these characters are displayed in the sequence in which the tones they represent occur in said theme.
