Hey, I just started mello last year..(2 years on mello so far..1 yr left)4 years of mb so far :P ) I marched clarinet for 2 years..then switched for the better..anyway
Tone Qualtity... :P :P .
The one think i can say that will most likely help (goes for all instruments idk bout flute) is to....
Open your throat when you play...Take a deep breath...
You can practice this by leting all ur air out then breath in (make sure your stomach goes out, chest mvt. must be very little. )...then out blow fast warm air... (u'll get lightheaded after doing it for a while )
idk just try that every day...and it's helped me on clarinet and mellophone.
