ABSTRACT:
An optical tone generator comprises sensing means responsive to light of different respective colors for selectively producing respective output signals corresponding to such respective colors, and a tone generator responsive to the sensing means for emitting a tone corresponding to the signal produced by the sensing means. In a preferred embodiment, fiber optic light conduits are disposed within an elongated baton for manual translation along a line of discretely changing colored strips to produce tones corresponding to the various colors. This device is particularly advantageous for teaching musical composition because it permits a child to vary pitch, duration and tempo by readily perceived variations in color, length and speed, respectively.
