One voice per part

In music, one voice per part (OVPP) is the practice of performing choral music with a single voice on each vocal line. In the specific context of Johann Sebastian Bach's works it is also known as the Rifkin hypothesis, set forth in Joshua Rifkin's 1982 article and expanded in Andrew Parrott's book The Essential Bach Choir. Choral works featuring SATB (soprano, alto, tenor and bass) vocal parts are consequently sung by four singers when this approach is adopted.
