This is originally written for A cornet. I have transposed to piano accompaniment, in order to avoid many sharps/flats in the Bb cornet part.
Also, I have performed the following changes:
after the modulation (to 2 sharps for the trumpet), there are some very strange chords in the piano which do not fit together with the trumpet solo. I have changed these chords in the piano part.
after a fermata it can be difficult to restart together with the piano accompaniment in a Play-along. Therefore, I have added some notes in the piano part.
