The influence of Schola Antiqua is evident in the name of the Chicago-based (well, obviously) ensemble Schola Antiqua of Chicago. This piece by Josquin apparently:
is regarded as Josquin’s most famous motet and one of the most famous pieces of the 15th century. The piece rose to extreme popularity in the 16th century, even appearing at the head of the first volume of motets ever printed. Its revolutionary open style featuring early imitative counterpoint and two-voice parts has added to its acclaim as one of the most influential compositions of its time.
