OH man, you are spot on Rad. Generally Claire and Vic help me sus out these oversights, but leave it to me ol to uncover this bit...!
WHAT are we talking about? Here it is...
At 4:08, the bass hand plays an ascending line, G ' A, G B D A, G ' A
I am playing it G ' A, G B D B, G ' A
This puts a B in the bass against the G in the melody. While this could work, putting on the A is better voice leading as that is the V of V that was popular back in the day - very easy on the ears.
I may have to do the video again. But first, a quick thank you to Jayesskerr, Jzzb8ovn, Markussz, Gusset, meugel, bachdois and of course, the thunder from down under Stickrad. I am so grateful to share this music on this instrument with this group - a pleasure and an honor.
Cheers and happy Tuesday.
