U"ni*son (?; 277), n. [LL. unisonus
having the same sound; L. unus one + sonus a sound: cf. F.
unisson, It. unisono. See One, and Sound a
noise.] 1. Harmony; agreement; concord;
union.
2. (Mus.) Identity in pitch; coincidence of
sounds proceeding from an equality in the number of vibrations made in a
given time by two or more sonorous bodies. Parts played or sung in octaves
are also said to be in unison, or in octaves.
&fist; If two cords of the same substance have equal length, thickness,
and tension, they are said to be in unison, and their sounds will be
in unison. Sounds of very different qualities and force may be in
unison, as the sound of a bell may be in unison with a sound
of a flute. Unison, then, consists in identity of pitch alone,
irrespective of quality of sound, or timbre, whether of instruments or of
human voices. A piece or passage is said to be sung or played in
unison when all the voices or instruments perform the same part, in
which sense unison is contradistinguished from harmony.
3. A single, unvaried. [R.] Pope.

U"ni*son (?; 277), a. [Cf. It.
