ABSTRACT:
A mute attached to a brass instrument has an inner surface shaped in such a manner that standing waves of representative harmonic tones have respective final nodes therein close to final nodes of the standing waves generated without the mute, and the pitch of the sound is hardly changed between a performance with the mute and a performance without a mute.
