A performance apparatus which can realize interesting performance with
game elements. Coordinates are designated in a matrix display input
section, and sounding data corresponding to the designated coordinates
are generated. Sounding of musical tones based on the generated sounding
data is instructed. Based on the designation of coordinates, a moving
route is set, and a moving ball indicating corresponding present position
coordinates on the set moving route among coordinates in the matrix
display input section is generated. At least when the moving ball has
reached predetermined coordinates on the moving route, sounding data
corresponding to the predetermined coordinates is generated, and sounding
of a musical tone based on the sounding data generated in association
with the predetermined coordinates is instructed.
