I got a question Mike.
Haven't figured how the post is relative to the subject line so please explain how any of the above makes a 13th easy??????
And inasking this, I may even get another wonder answered with a bit of luck.
A thirteenth is 1 3 5 flat7 9(11) 13 according to my book of chords.
And that is my wonder. What does the 9 (110 mean?
Are they optional choices or something?
Playing sol ti re ( 5 7 2) in C gives you the G chord.
