The QUARTET is typically structured as the full rhythm section, The TRIO-(piano/bass/drums) with vocalist, guitar, violin or horn as the fourth member.
This larger ensemble provides every bit of snap, pop and crack that you typically associate with the TRIO but with stronger vocalize, or stronger/clearer melodies usually stated by the guitar or saxophone or vocalist. The QUARTET is considered the fullest sounding four piece musical group.
