UMich Symphony Band -Michael Daugherty - Reflections on the Mississippi for Tuba and Symphonic Band 

yes

Nah, she's a woman; her horn is a beast. I know it's customary for soloists to stand, but I suggest that allowances be made for tubists as they are for cellists. Playing a tuba (not a sousaphone) standing up looks like rather effective weight training, but the concentration should really be on the music (but she plays superbly anyway).

She has a belt that does most of the work of supporting the weight of the instrument. You can see the connector clearly when she takes the tuba off at the end of the piece.

Didn't notice that. Thanks. It makes a lot more sense than what I thought she was doing.

Not a BEAST Lauren!... She is a Lady... Hadn't you noticed?... Perhaps you could do with some tutoring on manners. Shared on Google+

@@JoaoFurtadoCoelho777 @Joao Furtado-Coehlo I think you have misunderstood. Saying "[Person] is a beast" is a very common slang term used in America to describe that someone has exceptional playing ability on an instrument, and is pretty universally regarded as a compliment in this context. I'm pretty sure that most musicians in America, especially those of younger generations like Carol, would not be offended in the slightest by this comment, and would probably take it as the compliment that it is.

OMG Shut up.

She's wearing some sort of support belt. Right after she walks across the stage and lifts her horn, you can see her position the bottom bow onto it.
