Mixed Meter Boil-down!

DIVIDE AND CONQUER
UNITE AND RULE

Here's an audio clip of my teacher from DMA days, Mr. Ralph Votapek, playing the Ginastera piece I mentioned in today's noon WC section:
http://www.ralphvotapek.com/selections/01%20Ginestera%20Sonata%20No.1,%20IV.%20Ruvido%20Ed%20Ostinato.mp3

The meter is 3/8 + 6/16.
There are either 3 or 2 "big beats" per measure,  16th notes are the constant.

I remember hearing Mr. V. practicing this piece. Yup, subdivisions to the 16th, AND metronome!
This sounds like it would be immensely tedious, but I have done it for years upon years, and it actually takes LESS time than doing stop/start/stop/fall on the hurdle stuff in practice. Every incorrect repetition adds to the problem. Practice really begins once you've gotten the thing right!

Working with subdivided beats at a moderate (or moderately slow) tempo gives you TIME - time to see what's up ahead (your eyes should ALWAYS be ahead of your voice); time to fully comprehend what you're doing, and even time to keep a mistake from happening in the first place!

The neatest thing about subdividing madly in practice, happens when you have truly internalized the subdivisions. You then shift your awareness to the big beats, and THEN you shift your awareness to groups of MEASURES. The "macro" view, let's say.

Very interesting things surface from the Telfer Gloria when one gets to the "macro" level.

Y'all, I have learned ENTIRE PIECES using the metronome to click once for every note in a subdivided beat. As mastery increased, I would go "up" one level in rhythmic feeling until I was sailing along with the metronome clicking only once or twice per measure. THIS WORKS! IT WORKS! IT WORKS!
It doesn't work only with instrumental music. It works with vocal music!! It works with choral music! It will work with you. If you do it.

If anyone's interested in a personal demo of this method, email me. I will be happy to show you exactly how the monitored-subdivision practice method works.
