[musictlk] question about posture

[Kelsey Nicolay]

Hello,
For concerts, we pretty much stand the entire time which is for 
about 2 hours with a 15 minute intermission.  Our director 
instructs us not to stand with locked knees which I totally 
understand.  However, because of my music stand, I feel like I'm 
almost squatting down when I'm standing.  Therefore, it feels 
very unnatural for me to stand the way our director has 
instructed us to.  What do you think about this issue? Is it ok 
to stand without bending the knees as long as they're not locked? 
Or how can I make it more comfortable and natural to stand like 
the director wants us to? This is the first choir where the 
director has ever made a big deal about this.  Even my private 
voice teachers haven't made a big deal about this posture 
component.
Thank you,
Kelsey Nicolay
