The fifth volume in our complete edition of MarbrianoÔÇÖs music contains his Mass LÔÇÖhomme arm├®, based on a monophonic chanson used by as a cantus firmus in Masses by numerous composers from Dufay to Carissimi; the style of the setting suggests a date in the later 1480s. Orto frequently combines the popular melody in one mensuration with the other voices in another, showing an ingenuity that is more obvious to the eye than to the ear, and not always easy to express in modern notation. For four voices: SA/TT/BarB. x + 42 pages.
