Now, bouncing forward into the 16th century and beyond, here is some "classic" Renaissance polyphony with the chant on which it is based. If you listen to the plainchant and then to the polyphonic motet, you can hear the chant melody go by:

Chant “Sicut Cervus”: Chant "Sicut Cervus" "Like as the hart desireth the waterbrooks, so longeth my soul after thee, O Lord."

The motet by Giovanni Pierluigi da Palestrina, Sicut Cervus

Chant “Ave Maria” and Thomas Luis de Victoria, “Ave Maria”: Ave Maria

Here's an interesting one: Mr. Thomas Tallis, an exemplary English 16th c. composer, combines Sarum chant and polyphony in this lovely motet. Sarum (Salisbury) chant is different from Gregorian chant -- you'll notice the use of triple meter and also the very formal structure and limited range. Audivi vocem de caelo (I heard a voice from Heaven).

And from the 20th century: Maurice Duruflé (1902-1986: Ubi caritas

Thanks so much, AnAmericanMother!

You've given me a lot to listen to, and I'll have to try to carefully step through the links you've provided and your accompanying notations, to follow your points about them. (From all you've said here, I believe you could probably teach a whole course in these kinds of historical music forms, and it would be great to know all those things. Maybe you should set up an online school about them, for newer Catholics.)
