Mujitsu and Tairaku's Shakuhachi BBQ

So I don't know any of you particularly well, but it's blatantly obvious you each share a deep passion for the Shakuhachi, which would deduct that you're truly passionate about SOMETHING, of which a slipping handful of people in the world seem to be, these days. So, for my question you're all very useful.

I have been asked to write a very specific piece of music. It was due on April 1st. I had to request an extension till the last weekend of this month. Here's why:

I've been asked to write a 30 minute "Martial Arts Warm-up" piece of music. It is to be high energy and for any given practice. For 30 minutes. I sent them a 1:40 minute sample a few weeks ago and they said it was very good, but they began to loose interest about 40 seconds in, regaining it near the end. This is because it is progressive. Any given melody is generally short. It is all of your creative focus. I don't believe in the next 10 days I’ll be able to write 30 minutes of straight INTERESTING melody.

So... I need advice on several levels. I know everyone here is doing something esoteric. Are there any martial artists? Are there music enthusiasts? What inspires you in music, what can make it powerful for you? Some people like metal to get pumped up. Some people like the sound of a deep resonant church organ, some martial artists are very esoteric, some are very traditional and don’t like synthesizers or drum beats or overdrive guitars... you get the idea. I have to write something universally valid. This is why I sit at my music workstation and stare off into oblivion. What can I do?

I'm at about... 2:30. I've got a ways to go. I've written 5 meditation albums for this group and they're just taking off... I need to finish this, somehow. I don’t know if I’m looking for suggestions or advice… there’s just something I’m missing in my creative mind that isn’t triggered yet. How can I find something for everyone over the course of a steady 30 minutes?

Scott,
