In playing the actual music, the head refers to any time the band or musician plays the theme to the song. Usually this happens once or twice at the beginning and the end of a performance. For example, many Clifford Brown recordings characteristically feature a short piano intro, the head, several choruses of solos and a recapitulation of the head followed by an outro coda. Although it most commonly is, the head does not need to be played at both the beginning and the end of a performance, and is occasionally played in the middle, for instance between solos.
