Here is a little piece I wrote about 6-7 months ago. Its a piece for Bb trumpet and Piano. I am afraid I do not have score for this.
It has a simple form, simple theme and a simple development !
This music is somewhat written by the more Jazz side of me. Most of the chords and progressions are jazzy. For example Poly Chords ( Ex: A maj7 over G major), Minor 9th's, minor 7th's and some more bunch of chords that I cannot recall right now.
The theme was simple as it could get. But I did try to explore the more possibilities that could be done with the material at hand. The scalic passages are nothing more than octatonic scales running up and down, to make it rhytmically more interesting I used diffirent note values for each instrument.
What else can I say... Instrumentation ? Well, I was a bit hard on the trumpet, I think its a bit difficult to play this. I had a workshop where they played this piece, the trumpet player was very good. So I am sure it is playable.
Enjoy
