noun
Rare term for a musical rest symbol. In modern Japanese, 休符 or 休止符 is overwhelmingly more common.
楽譜で「停音符」という表記を見かけることはほとんどない。
You almost never see the notation 停音符 in a musical score.
Another common term for a rest, especially in older or formal contexts. 停音符 is far less frequent.
Compound of 停 (stop) + 音 (sound) + 符 (symbol). The exact historical derivation is uncertain; the spelling is conventionally associated with the meaning of a musical rest.
