Abstract
The disclosure provides a detection device, a percussion instrument, and a detection method. The percussion instrument includes a head; a base that has at least a portion formed in a curved shape and that is in contact with the head in a direction in which a curvature of the curved shape is changed with a vibration of the head; and a film-shaped piezoelectric sensor disposed on the base.

A percussion instrument comprising:
- a head;
- a base that has at least a portion formed in a curved shape and that is in contact with the head in a direction in which a curvature of the curved shape is changed with a vibration of the head;
- and
- a film-shaped piezoelectric sensor disposed on the base.

A detection device comprising:
- a base that has at least a portion formed in a curved shape and that is in contact with a displacing portion of a musical instrument in a direction in which a curvature of the curved shape is changed with a displacement generated by performance of the musical instrument;
- and
- a sensor disposed on the base to detect a change of the curvature.
A detection method comprising:
- bringing a base that has at least a portion formed in a curved shape in contact with a vibrating portion of a musical instrument in a direction in which a curvature of the curved shape is changed with a vibration generated by performance of the musical instrument;
- and
- detecting a vibration of the vibrating portion of the musical instrument by a film-shaped piezoelectric sensor disposed on a portion of the base where the curvature changes.
