So, to beat a dead horse,
I take my Fake C sheet of say Blue Christmas in G
Enter the Chords
F9/F9-Fmaj9/C7
Transpose the Chords down 1 Tone
and get
Eb9/Eb9-Ebmaj9/Bb7
and I can play the notes as is on my sax
A/A-G-A/E-G-, but they will sound one tone lower and match the new chords in BIAB.
Please say it is so
:-)
