More considerations

I've been thinking some more about the form, and about the different sections. My original intention was that the letters A, B etc (see "The Blues" below) would represent different thematic material - and I was mostly thinking in terms of melody and harmony, I suppose. But now, since the "rhythmic layer" has been applied, it's obvious that the rhythms and tempos are in fact thematic material as well.

I also realize that, the way the piece looks now, there will be quite a lot of information in a relatively short time. Lots of stuff happening. So in order to balance it, I suspect I'll have to make either the melodic or harmonic content - or perhaps both - really simple and concentrated. Which, I think, is a good thing anyway.

At this moment, I have three different harmonic concepts that I'm choosing between. Two of them I have experimented with in previous compositions, while the third idea is completely new. Perhaps later I can give you more details about it. First I want to decide which one to use - or if they could possibly be combined somehow.

Another thing to consider is the element of improvisation, which of course is a crucial aspect of jazz music. Where in the piece should I make room for improvising, and in what way? Perhaps I can use improvisation as a thematic element as well?
