Missae L'homme armé

Missa L'homme armé is a mass by Franco-Flemish composer Johannes Ockeghem, composed around 1460. The work exemplifies mid‑15th-century polyphony, employing an extended cantus firmus and dense imitative counterpoint that showcases Ockeghem's use of long-breathed melodic lines and complex mensural relationships, and it forms part of the tradition of L'homme armé masses that influenced later Renaissance composers.
