Dave thank you for your extended explanation. From your experience it seems it doesnt matter which finger to put first and there are no rules according to your text, am i right?
And I guess you're right as I moved on to the next video (C to G and D to G) where Lisa tells that the priority note is not a thing to worry cause of the open string that is the base note.
So thanks again and remember practice doesnt make perfect, PERFECT practice makes perfect :-)
