Well, as a classically trained trombonist, I simply must disagree with you in this matter. The fact is that it all can be played, and with a lot of practice, it could even be played fairly well. But given certain circumstances, it proves to be exceedingly challenging to a non-virtuosic player.

For instance, the 16th note runs wouldn't be nearly as hard if they were in a different key. To go from gaba twice requires the trombonist to go from 4th to 2nd to 5th to second, which is not an easy exchange at that speed. I suppose it the part were down one half step, it would simplify things (5th 3rd 1st 3rd is an easier transition).

In regards to the heavy use of glissando toward the end, just doesn't allow much time to reset the emboucher to begin the next slide. However, to simplify it, one could write it as a lip slur, or a drop off of sorts, which most trombonists could probabably handle.

The issue with range is not necessarily one of comfort, as most trombonists should be able to approach Bbs, but the fact is that it doesn't make adequate use of the trombones middle to low range, which is what a trombone is most commonly recognized for. I don't think you would want a jazz lead trombone sound on this piece.

Then the sudden drops, usually to low gs, is simply a much larger leap than it needs to be. I would suggest taking the lowest notes up an octave unless they are being approached by a descending line. Other than that, the range is quite good, and the melody is exceptional.

In my opinion, it certainly can be played, but unless it is being played by Christian Lindberg, it will never sound as nice as you want it.
