Hello. I haven't posted here in a while but I just had some questions. I really need to improve my range and endurance. I have been putting this problem aside for a while but I really wanna go after it now. I started today with playing longtones/ lipslurs/scales very softly. Is this the way to approach it? A lot of people tell me I have a very dark, nice sound, but I really want to improve range and endurance so I can be a better overall player. I'm willing to work hard for this. Also, I play with a slight upper tilt and I think I am an upstream player, does this have anything to do with this? Any suggestions? Thanks!!
