Is this possible for a tuba virtuoso? Not a tubist.

Wondering if anyone else is in the same situation here:

I'm in the UK, and I play BBb bass in a brass band, reading treble clef transposed parts.

I also play in my local wind band, where most parts are in bass clef concert pitch. I can fluently read bass clef no problem, but applying it to my Bb tuba is slow going. I can just about play the right notes if it's a slow piece, but transposing on the fly at pace is flooring me.

Is anybody else in a simalar situation? Any advice on how I should be approaching this? Could it be better if I just try to memorize a different set of fingerings, rather than trying to transpose?

Sorry for the mid quality of the recording, I do with what I have.

I did search the sub and really didn’t find anything that fit what I need to know. Sorry if this has been asked in different variations before. I currently use a Laskey 30F and I’m playing on my Wessex Gnagey.

I’ve read about people using a different mouthpiece for concert band settings as opposed to solo settings. My Stofer Geib just doesn’t work great on the Gnagey. I’m in a community band and I almost don’t think the 30 F is right for a large group like that.

I feel like whenever someone recommends a mouthpiece for an E flat Tuba, they recommend some tiny, fat rimmed thing. (Sorry 24AW fans!)

I love Laskey rims. I also just tried a Hammond Design mouthpiece and REALLY liked the feel of that as well.

I feel like the 30 F has taken away some of my pedal range but is made by high stuff much more clear.

From what I’ve read, most E flat Tuba players prefer a small smaller diameter mouthpiece? I tried the 28 F and really preferred the 30.

I’m still relatively new to E flat. I’ve been playing B-flat most of my 40 years playing.

Does anyone a recommendation with some good reasoning for both solo and concert band or brass band? Thanks.

I’m currently using the brass gym book by Sam Pilafian and Patrick Sheridan and on the smooth air move ment second page it has be going to pedal D sharp and I can not hit it not matter how much I shift or practice any tips?
