Abstract
A musical-tone-control apparatus having a baton which is provided with an acceleration sensor, and which is swung by a performer is provided. The intensity of a swing of the baton is detected by the acceleration sensor, and controls the tone-generation timing and tone elements such as tone pitches, tone volumes, or tone colors. The intensity of a swing is detected after a predetermined interval has elapsed from the beginning of a swing. As a result, a delay of detection of the intensity due to the inertia of the swing is eliminated. Hence, the swings and the tone-generating timing of musical tones are in harmony, which allows the performer to enjoy a natural feeling of performance.

A musical-tone-control apparatus comprising:
- a swing member adapted to be swung by a performer's hand;
- acceleration-measuring means, provided in said swing member, for measuring acceleration produced by a swing;
- start-point-detecting means for detecting the start point of a swing of said swing member;
