Vladislav Blazhevich "70 Studies for BB flat Tuba" transposed for Horn in F. I've been posting these as I get them done, in the order worked on. [If you previously downloaded copies with explicit metronome markings, please ignore them. They are not authoritative and have been removed from the files now posted. Also, I've been correcting transcribing errors as I find them. If you find a mistake, please contact me and I will fix it!]
