ABSTRACT:
An apparatus having a calculating mode and a music generating mode and which is adapted to be selectively disposed in either the calculating or the music generating modes. The apparatus has a housing and a keyboard layout which simulates the housing and keyboard layout of an electronic desk-top calculator. The keys on the keyboard are assigned numerical and functional designations comparable to those found in a desk-top calculator, and additional designations symbolizing the musical notes generated by depressing the keys. Each key can perform the numerical or functional operation, or generate the musical note, associated with its respective designations. Thus, a musical score can be correlated to the numerical and function keys of the desk-top electronic calculator, and a person who is able to operate a desk-top electronic calculator by "touch" will be able immediately to play music by "touch", rather than by hunt-and-peck techniques.
