I'm a beginner and blowing in a soprano is too difficult to me. Escpecially for low E and F. So I can't give you an answer about the sound. It's bad because of me . I think also that the mouthpiece is a little unusual comparing to alto and tenor ones. The reed is larger than the space between the side rails. And it exceeds them on each side by 1 or 2 milimeters. I never played on another mouthpice than i can't compare. Concerning other parameters I found the keys soft and the horn easy to hold (comparing to no oher :albinoThat's cool, and one made it all the way to Algeria !Do you like the soprano ?
