There are no mystical components involved in jazz music — mostly it’s about improvisation and swing. And what holds true for the piano, bass or saxophone also applies to the human instrument — the jazz voice.

This Friday, Jay Clayton, who refers to herself as “a jazz singer/performer who composes and teaches” will present, in recital format, three Peabody students majoring in Jazz Voice and Jazz Standards. The study of Integriti Reeves, Amanda Bloom and the school’s first vocal jazz major, Lauren Shusterich, involve the mastery of the vocal jazz repertoire.
