In music, a solo (from the Spanish and Italian based-word: Solo, meaning alone or by yourself) is a piece or a section of a piece played or sung featuring a single performer, who may be performing completely alone or supported by an accompanying instrument such as a piano or organ, a continuo group (in Baroque music), or the rest of a choir, orchestra, band, or other ensemble. Performing a solo is "to solo", and the performer is known as a soloist. An instrumental solo is often used in popular music during a break or bridge to add interest and variety to a part of the song without lyrics.
