ABSTRACT:
An electronic apparatus for teaching and reading music comprises: a tone generator connected, via logic control gates, to a system for reproducing the sound; a keyboard for selecting the notes of the scale to be generated each key of which may be compared to a symbol of the corresponding note which is located on or adjacent to that key; and at least one set of control buttons for selecting the time duration of each scale or rest note, with each control button designated by a symbol of the time duration of the scale or rest note. Each key or button also has a corresponding electronic visual display (LED) to indicate its selection. A multichannel, pluriaddress, memory device is provided for WRITING-in and READING-out musical data. The apparatus also includes a mode selection switch with which to select operation of the device for reading or writing. A variable frequency generator sets the timing of the music to be played.
