A small jazz group is a musical ensemble consisting of three to six musicians. The most common small jazz group is a TRIO, which consists of three musicians, and a sextet, which consists of six musicians. Trios typically consist of a piano, bass, and drums, while sextets may include additional instruments such as a trumpet, saxophone, or guitar. Both trios and sextets are popular in jazz music, and can be heard in many jazz clubs and festivals.
