If you are playing a note that sounds like that, make a mental note to avoid playing that note in the future-and learn a way to fatten it out, later.
You should showcase notes that sound like notes you would enjoy hearing.
I'm so lucky I get to come up with my own lines in our trio-The Creekers.
I try many riffs that prop up a phrase and usually choose the one that my tuba sounds best playing. We take no music onstage.
If you lack that happy choice, make a list of the notes coming out of your tuba that are stinkers. Keep trying to hit those stinkers from above, below or jumps from everywhere-try alternate fingerings-slur. Devote some time to drilling the worst ones at every practice opportunity-sounds crappy but really helps.
I found a horn that has the right range for tropical rock and enjoy the lows that are right down to the bottom of my real range. I chose to sacrifice highs to sound better low and velvety. It's nice to solo up high on my Eb tuba but here lately I have been enjoying playing solos down low with an "in your face attitude".
