I found how to have my Bari Sax in bass clef in concert pitch and transposed correctly in transposed pitch.
My question is about the transposition terminology Edit > Clef > Transposed Pitch > “Treble Clef 15 Above”. 15 what? It’s not half or whole steps and I cannot figure out how this translates to an octave and a sixth. Things show up correctly on the score and in the part, but I was wondering about the interval cited because I did not try it except in desperation.
I am probably missing something very simple. Please advise. All help very much appreciated.
