THE 4 VOICES OF SATB AND THEIR RANGES

Here are the four voices from high to low: Soprano, Alto, Tenor and Bass (abbreviated as SATB), as they appear in standard notation. Four-part harmony is traditionally written on the two staves (treble and bass), with the treble staff containing the Soprano and Alto voices (with their stems up and down respectively), and the bass clef taking Tenor and Bass (again with stems up and down respectively).
