I am in Aspen right now , just got here 2 days ago. I have noticed that my long phrases are getting hard to get through. The audition here at the festival is on sunday. Are there any breathing exercises I can do to help this? Also.. One of the excerpts is shosta 1 , the slow muted slow. I only have a wick straight mute. I wish i owned a trumcor lyric or a montreal mute, but i dont. Should I try and play really soft, play mezzo, or put a crown bag over it? It is really hard to play it soft, especially with the air up here. Thanks.
