Main Page | See live article | Alphabetical index In music, solo means to play alone. This does not necessarily mean that no one else is playing at that time, but that the soloist's part is more prominent. In jazz is it common for each player to improvise a solo in turn. A related term is soli, which means that a whole section of a musical ensemble is playing the same thing. This article is from Wikipedia.
