Missa "De plus en plus", Chansons

Missa "De plus en plus" is a mass by Flemish composer Johannes Ockeghem, composed in the mid-15th century. The work exemplifies mid‑15th-century Franco‑Flemish polyphony, featuring dense vocal writing, modal harmonic language and imitative techniques that illustrate Ockeghem's approach to cyclic mass composition and his role in the development of Renaissance polyphony.
