I had one of those B&S-like Miraphone F tubas, and also owned a B&S Symphonie (still owned today) at the same time.jtm wrote: Tue Aug 29, 2023 1:50 pmYour quips make me feel lucky I found one. Open C in the staff can be made to go sharp (more easily than if played on 4th valve, for example), but it doesn’t go sharp on its own; the natural tendency is to be in tune with the Fs above and below it. This is the 181 style that they didn’t make very long, shaped like a PT-10 except that the valves aren’t graduated. I was told that Dave Kirk had it for a while.bloke wrote: Tue Aug 29, 2023 10:11 am Miraphone F tubas:
just as well-made (various models) as everything else Miraphone mades, but (me...??) I've just never played one (nor too many other F tubas) whereby the second-space C didn't require a good bit of attention.
I sold the Miraphone to a friend who kept it for a while.
It was a good bit of work for me to play.
I'm pretty sure that it was even larger than a PT-15, because I have an easier time making a PT-15 "go" than that particular instrument.
Even some PT-15 tubas feature a tendency for that C to ride sharp. I can't explain it, but I have to play it with a certain "embouchure" (DIFFERENT from "lipping") to get that pitch in tune - when playing quite a few PT-15's.
