what is the first known polyphonic setting of all the sung movements of the mass ordinary
Mass (music) Two manuscripts from the 14th century, the Ivrea Codex and the Apt Codex, are the primary sources for polyphonic settings of the Ordinary. Stylistically these settings are similar to both motets and secular music of the time, with a three-voice texture dominated by the highest part. Most of this music was written or assembled at the papal court at Avignon.
Baroque music By incorporating these new aspects of composition, Claudio Monteverdi furthered the transition from the Renaissance style of music to that of the Baroque period. He developed two individual styles of composition – the heritage of Renaissance polyphony (prima pratica) and the new basso continuo technique of the Baroque (seconda pratica). With basso continuo, a small group of musicians would play the bassline and the chords which formed the accompaniment for a melody. The basso continuo group would typically use one or more keyboard players and a lute player who would play the bassline and improvise the chords and several bass instruments (e.g., bass viol, cello, double bass) which would play the bassline. With the writing of the operas L'Orfeo and L'incoronazione di Poppea among others, Monteverdi brought considerable attention to this new genre.[16]
