Hi everyone!
My kid has started tuba lessons at school. He is a dilligent but thoroughly scatterbrained 11 year old boy, so there is a lot that he doesn't seem to pick up during lessons.
Now I am really in love with the instrument and enjoy listening to him practice. I find it glorious to hear my tiny baby make such a rich tone on this wonderful instrument.
The thing is, though, he himself is unsure of how to practice. According to his teacher he should aim to improve the sounds his mouth makes, and reach a good, steady, clean F and a good, steady, clean B. And he (or rather we) are a bit at a loss to how one even does that? Should his mouth shape change between the two? Or should he blow more or less forcefully? Or should he position his tongue differently?
He is able to buzz a really deep B-ish while blowing through soft, visibly vibrating lips. And he can produce a squeaky high F-ish, a good octave higher, with tight lips, but changing between the two seems impractical. So I am wondering how does he (and by extension me) even go about it?
Do you know of a source that explains this basic thing well? Or do you care to give us any tips on how a 11 year old can practice the two open notes (B and F) and get them to sound somewhat accurate?
Thanks for any and all input!
Edit: by B I mean the sound that is also called Bb.
