My high school marching band is doing 1812 overture for our marching show this year. Our last note of the show ends on f,a, and c and my band director would like me to play the f above the c. I can hit up to the e no problem but for some reason that f has got me. Does anybody have an y tips for extending my range about two notes so i can hit the f and g solid? I am hoping to play it for marching festival, that gives me about a week -_- It might not even be possible. Thanks

play slured
G,A,B,C and back down until thats down easy
A,B,C,D till thats easy too
B,C,D,Eb till thats easy
C,D,Eb,E till thats easy
C,D,Eb,E,F
thats how i got my higher range down...although ur gonna need to do that alot if u wanna do it in a week
