Wow, that's a fantastic ensemble. 20 trumpets is going to be pretty fun to work with...
What made me smile though was the 15 percussionists - we're going to make sure they have the time of their life playing this arrangement of yours.
So here's what I'd like to do from here on in. Because you've already got yourself an arrangement of this piece for mallets, I'd like you to start by creating a score which will encompass your entire concert band, and then keep it handy. More importantly, I want you to look over your piece and get a firm idea in your mind of how you want to orchestrate (I'll use the term since "concert-bandistrate" sounds a bit tacky) it and whether or not you want it to be structured the same way as the mallets version.
When you know how you'd like it to end up, post a brief written summary detailing how you want it to be structured, how you'd like it to develop and what you're intending with the piece in terms of mood, energy level, etc.
Use any terms, words or formatting that you need to express yourself best. The reason I ask you to do this is because having a written outline helps keep a sense of direction - otherwise with such a large ensemble it's tempting to just sort of "go nuts".
Also, thank you for allowing this lesson to be public. Anyone else who is following the thread and is interested in participating, please either post to say so or Pager/PM me about it and we'll see about tailoring the exercise to help you as well.
No set deadline, but try to have it posted within a week if circumstances allow; this isn't a major thing.
Good luck
