TREBLE
, in Music, the highest or acutest of the four parts in symphony, or that which is heard the clearest and shrillest in a concert. In the like sense we say, a Treble violin, Treble hautboy, &c.
In vocal music, the Treble is usually committed to boys and girls; their proper part being the Treble.
The Treble is divided into first or highest Treble, and second or bass Treble. The half Treble is the same with the counter-tenor.
