Dufay/ Ensemble Musica Nova - Flos Florum

Like many of his contemporaries, Guillaume Dufay was greatly devoted to the Virgin Mary. His Marian works comprise liturgical pieces sung during the Mass or the Office, but also religious motets written to new poems. It was probably during his first period in the chapel of the dukes of Savoy that Dufay produced a complete cycle of polyphonic hymns for the Office of Vespers of the principal feasts. Their interpretation obeys the principle of alternatim chant, that is to say alternation between monophonic odd-numbered verses, sung in plainchant, and even-numbered polyphonic verses. Dufay employs here the techniques of composition already in use in the fourteenth century. The liturgical melody is sung in the highest voice but appears transformed according to the principles of paraphrase: the composer's inventive contribution, in this context, resides in the flexibility of the mensuration (often ternary) and the grace of his ornamentation. The other two, lower voices accompany it in a virtually homophonic style. The influence of the improvisatory practice known as 'fauxbourdon' is manifest. In it's simple form, the melody of the cantus is doubled by the tenor and the contratenor, respectively a sixth and a fourth lower. The result is a succession of highly characteristic chords, interrupted only for the cadences.
