ABSTRACT:
An electronic musical instrument sequentially calculates a plurality of partial tone signals which are amplitude-modulated by a plurality of time window signals, on the time division basis, such that these partial tone signals are synthesized to form a musical tone signal. The instrument includes a circuit means for producing a plurality of predetermined time window signals, an another circuit means for producing a plurality of predetermined partial tone signals and modulating means for modulating the partial tone signals with the time window signals on the time division basis. This instrument makes it possible to form a musical tone having a great number of harmonic components with a simple circuit construction.
