Manny, I was asked to perform the Leopold Mozart Concerto at a program in early December and I would like to know if you know any history on this selection. The arrangement I have is not very difficult, and is in the Key of Bb Concert (which I doubt is the original key). I have to say that it is a nice arrangement, obviously stolen from a college library, and is listed as a grade V solo (which I find hard to believe). Other than the fact that it lays above the staff for a majority of the piece, it really is not that hard and could be easily performed by a talented high school student. My main question is the horn selection -- would you play it in C trumpet or on the Bb side of a piccolo. It sounds great on both horns, but the tonality is totally different. I really can't decide which I like better and would like to do it on the more historically accurate instrument.
