Yes, Rosetti no.5 is some challenge, as it is in E. Using a lot of F-side might help much, as all arpeggios go on 2, and the valve 2 is the most engaged there. Using the Bb-side (2nd valve switches it to A-horn) for some top notes or when fingering might be easier even in the low range, a great help.
BTW, what kind of edition do you use ? The Leloir - KaWe ? Where does the orchestra material come from ? Just a question. Enjoy the conversation with you. _______________________________________________ post: [EMAIL PROTECTED] set your options at http://music.memphis.edu/mailman/options/horn/archive%40jab.org
