Other forms: trios
A trio is a group of three. A jazz trio, the trio of friends, a piano trio.
In music it names both the players and the piece written for them, and a piano trio is piano, violin and cello rather than three pianos, which surprises people. In general use it is simply a neat word for three of anything.
