The above video is a modern recording of Vittoria Aleotti's "Angelus ad pastores ait" from her volume of motets, Sacrae cantiones, the first known published sacred music by a female composer. In it, the alternating chordal and imitative sections can be easily identified. Additionally, the use of instruments to fill the role of tenor and bass voices would have been typical at performances in the convent, particularly in a worship oriented setting.¹
