We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Tallis' "40 Part Motet" - officially Spem in alium numquam habui (c.1556) is a Renaissance motet, not a medieval motet. Thus no real rhythm, but plenty of flow.
Mrs. BD and I had to hustle down to The Cloisters after church to hear their special installation of Tallis' most famous work. One speaker per voice - 40 speakers - and you walk all around and hear each individual voice, or stand in the middle to hear the blend in the acoustically-superb old stone Spanish apse. We did it 2 1/2 times.
It is a popular event. Most people listen to it twice.
I maintain that the Renaissance "motet" is a completely different form of Gregorian based chant rather than a true motet as was practiced in the Medieval period. The Renaissance form is actually a polyphonic madrigal in which anywhere from 6 to 8 voices work in counter punctual harmony as opposed to the Medieval form that has two (occasionally three) voices that sound a bit chaotic in practice. Also the Renaissance form is more liturgical than the Medieval which is much more pastoral.
Still, it is beautiful when done correctly - call it what you will, it sounds wonderful.
