A three-person band, also known as a TRIO, is a musical ensemble consisting of three musicians playing instruments such as guitar, bass, drums, and keyboards. This type of band is often used in genres such as rock, jazz, and blues. The term 'TRIO' is derived from the Latin word for three, trium. A three-person band typically consists of a lead singer or instrumentalist, a rhythm section, and a percussionist. The lead singer or instrumentalist is usually the main focus of the band, while the rhythm section provides the foundation for the music. The percussionist adds texture and color to the music.
