This article is about the musical term "solo"; for other uses, see solo.

In music, solo means to play alone. This does not necessarily mean that no one else is playing at that time, only that the soloist's part is the most prominent. In jazz it is common for each player to improvise a solo in turn, while others continue to play but more quietly.

A related term is soli, which means that a whole section of a musical ensemble is playing the same thing at the same time.
