Abstract:
1. A musical instrument, comprising: a music-playing component to be held by a player, and including a light-emitting part that emits light and switches off; an image-capturing device that captures an image of an image-capture space that contains the player holding the music-playing component; a sound generating device that generates sound based on a position of the light-emitting part while emitting light in the image-capture space captured by the image-capturing device; a detector that detects a start and an end of a down swing movement of the music-playing component by the player; and a light-emission controller that (a) controls the light-emitting part to emit light when the detector detects the start of the down swing movement, and (b) controls the light-emitting part to switch off when the detector detects the end of the down swing movement.
