4 piston/Thumb rotor #5 - a possible alternative?

Postby barry grrr-ero » Sun Jun 02, 2019 3:53 pm

I'm sure somebody, somewhere has experimented with this. Since the rotor fifth valve is often times of a larger bore size than the pistons, would it not make sense to experiment with swapping valves 4 and 5, i.e. make the thumb rotor the fourth valve and the usual piston fourth whatever configuration you like for #5?

Fingering wise, anything that combines 4 and 5 would remain the same. On a C tuba, your 2-3-4 low E natural would become 2-3-5. That's not so bad. However, the current 2-3-5 notes would become 2-3-4 and I guess that could a bit of a pain. Anyway, . . .

Also, for those who might think a rotor fifth valve couldn't be placed at the back of the cluster on a rotary valve tuba, have a look at the Willson Eb that Bloke had up for sale, once upon a time. viewtopic.php?f=4&t=72696

I have no idea why I sit around thinking about these things. I don't dream about 'em.

I'm not sure that it's ever really been determined that an expanding bore through the valves (regardless of the length or size of the instrument) is necessarily an advantage.
