Abstract
The generating function cos[Z(t).multidot.sin(.omega.'t)] of Bessel functions is utilized as a modulating function for a fundamental function sin(.omega.t) in synthesis of a musical tone including many harmonic (over tone) components, wherein Z(t) is used as a modulating index. The modulating frequency .omega.' in sin(.omega.'t) of the modulating function cos[Z(t).multidot.sin(.omega.'t)] is selected relative to the fundamental frequency so that w'=n.omega. wherein n is a half integer or an irrational number.
