MUSICAL PERFORMANCE DEVICE, METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a musical performance device capable of controlling sound volume properly by reflecting intensity of a swing movement even when a virtual sound source is arranged vertically in a virtual space.SOLUTION: A CPU 11 calculates the maximum value of an angular speed of a stick part 10 during performance operation on the basis of an angular speed obtained by an angular speed sensor 123, calculates the maximum value of acceleration of the stick part 10 during performance operation on the basis of acceleration obtained by an acceleration sensor 122, and controls the sound volume of musical sound to be pronounced on the basis of the calculated maximum value of the angular speed and maximum value of the acceleration.
