If you listened to the recording of Two Pages that I expect you might have, then I'm sure you realised it was twice as fast as it was already. It's actually very relaxing at the appropriate tempo and has an entirely different effect. With that said... I think 9 Bars sounds a little too fast to me... but I think that may be because I don't like the choice of voice. Sounds like panpipes or something... not sure what you have it set to, but because it uses that sound it comes off as highly unnatural. It might work lovely with a more electronic sounding voice (as if MIDI isn't bad enough, but you know what I mean.) I'd still say I'd like it a few clicks slower.

As it is it sounds a little hectic and I don't get the same thing from it as I do from Glass' minimalism. For one thing, your approach at making a shorter work hindered my full appreciation of the concept. When I listen to Two Pages and some other similar Glass works (heh, pun intended) I get to sit there and really let it soak through me for the full 8 to 20 minutes. About halfway through I really start noticing more things and beginning to appreciate what I am perceiving, even if I didn't what exactly what it was I was perceiving. With 9 bars... the changes from "bar" to "bar" are rather drastic and even come off to me as random, and the whole piece is over in only 3 minutes. As far as an emulation of minimalism I felt a little jipped. As far as a work simply inspired by Glass', then hats off to you.
It would be interesting to see the score to this, not sure how you notated it, also makes a lot more sense to me when I'm looking at the notes to this stuff while I listen. This sounds quite sophisticated, actually, so all the more reason why I'd like to see.
I saw the 2 Pages video a day or two before now, so it's fresh in my head. I'm glad somebody is drawing off of Glass for inspiration. He used a lot of interesting concepts in his music. I'd like to see more people play around with these kinds of ideas --- see what they can stir up.
