A composition written for three voices and instruments performed by three persons.

A work or movement for three instruments or voices.

Originally a light-hearted peasant dance in the seventeenth century French opera performed by two oboes and a musette (a bag-pipe) or bassoon (i.e., three instruments). In a symphony, it is the middle section of the minuet movement usually in the subdominant of the key of that movement and performed by the wind instruments (but not necessarily by only three of them).
