OK, Robert - you stumped me.

Copied this recent post from tuben:

What is hilarious is reading the trumpet player posts trying to figure out what to do with six-valves (3+3).

Well, crap. I can't say I know for sure myself. I tried to search for posts on the 3+3 configuration, because I do remember this as a discussion item in the past. Couldn't crack the code, and I am out of time now, so I decided to bring this up (yet) again and tap into the trapline later. There is a more-or-less official protocol for how the 3+3 works. But what is it? As I recall it is NOT "right hand like a trumpet, left hand for wrong notes" - but that is pretty much all I DO recall. Never having actually played one.

This should help. I'm sure if you grow up with the system it is easy, but growing into it would be hard. YMMV.

Briefly, but then NPH ruined it for you.

The Anton Dehmal's Soehne 3+3 F-tuba, although the location may have been in question for a while, has been returned to Symphony Center and isn't, and never has been submerged in Lake Michigan, regardless of what a link in this thread indicated. The instrument is in excellent condition, even with very good lacquer still, although it would need a good servicing prior to being used again. As traditional European F-tubas go, it really is not a bad player in my opinion although the fingering patterns would take a bit of getting used-to.

OK - so it varies, but the instrument that Chuck linked to works like so: working down from the top, 1, 2 and 3 (left hand) are whole step, half step, and one-and-a-half steps respectively. Then 4, 5 and 6 (right hand) are one-and-a-half, sharp half step, and two-and-a-half steps respectively. Thanks, Chuck.

Except for the French Teapot in C - the best I can figure out the code is:
1 whole tone
2 half tone
3 two tones
4 two and a half tones
5 half tone
6 three and a half tones
