An electronic percussion instrument includes input means, correction
information storage means, and musical tone generation means. The input
means allows for vibration information, which expresses a vibration of an
operator, position information, which expresses a position of the
operator, and standard position information, which indicates a standard
position of the operator, to be input. The correction information storage
means allows for correction information to be stored that is based on the
position information that has been input in the input means that
corresponds to the standard position information that has been input in
the input means. The musical tone generation means allows for the
generation of a musical tone in conformance with the position information
that has been input in the input means that corresponds to the vibration
information that has been input and the correction information that has
been stored in the correction information storage means.
