GG, 3 valve contra fingerings

[Hank74]

Hello again,

I've asked this question before, but wish to ask again given that I now have a 3 valve Dynasty DEG GG contra. Simply put, what are the fingerings I need to use when playing bass clef notes with this contra I've got? I've heard it's the same as a BBb tuba. But I also have a chart saying they are 1/2 step off. Could someone here provide clarification here?

Merry Tuba Christmas. My concert is tomorrow.

Elephant, you are correct in saying I am only reading regular published bass clef music when playing my GG contra. I already printed out your chart from before and it has helped. I just need to keep working on those fingerings and getting them down. It's like learning a new language after all these years knowing the BBb fingerings. But what does the 3rd valve on my contra do for me? That's the big question I've got.

Elephant, tonight I got to play this GG contra some more and now seem to get the hang of it. I've got the middle Bb, F, and pedal Bb down. I've also been using the fingering chart you sent me. It was just a matter of practice. I hope to be fluent in GG fingering very soon. Thank you for your help!
