I have a piece of music that I'd like to find the title of but I only have a midi transcription. Shazam or something like it won't work because it's some sort of classical(? I really have no idea) piece. The music doesn't have a composer or title on it. There's a chance that it's an original piece. I have a feeling that it's from a book like Arban because of its length. I've already tried reverse image search.
This an exercise named DU STYLE which is No. 2 from Trente Six Études Transcendantes pour Trompette by Theo Charlier published by Alphonse Leduc.
