Balay's “Contest Piece” is one that is performed by most intermediate trumpet players at some point in their career. It is on many, if not all, jury lists and conservatory exam requirements and has been recorded by many professionals as well over the last half century. This edition has the trumpet part and piano part in one convenient file with page turns accounted for. All you need to do is hit print, hand half to your accompanist, and start playing.
The first page of each part is available in the samples to the left and immediate PDF download above.
