Manny and others,
Ive been playing with the orchestra at school on first part. We are playing a peace called FESTIQUE. There are a few parts that are above the staff in the high A region and there are giving me some trouble. When ever i play them the director tells me to play with a "rounder" sound and i dont know what he means or how to acheive it. its hard on one of the runs because i have to go up to the A playing at mp. What can i do to get a round sound above the staff

. Are there things i should conciousley be thinking about or is it just PRACTICE. and if so what should i practice.
-Thanks in advance
