ABSTRACT:
An automatic performance apparatus has a memory, a reading out circuit, a parameter creating circuit, and a tone generating circuit. Initially, basic performance data corresponding to the basic performance of a musical piece and musical expression data corresponding to musical expression to be imparted to the basic performance are stored in the memory according to the progress of the musical piece. Next, when the basic performance data and musical expression data are read out from the memory by the reading out circuit in due order, the parameter including musical expression is created based on the read out basic performance data and musical expression data in the parameter creating circuit. Accordingly, this parameter is supplied to the tone generating circuit and a musical tone signal to which musical expression is imparted is formed in the tone generating circuit.
