this is, in fact, the correct way to play the tuba - with extreme force. to hell with all the weakling bourgeois players that are afraid of playing too loud. to get this instrument to sound the way it ought to requires every ounce of lung strength and emotional catharsis you can pull out of the innermost depth of your absolute being. a proper tuba performance should require an oxygen tent.

it's a shame the quality is bad. i need a good sample to get the dynamics right; i'm trying to figure out how to make my guitar sound like one.
