Can anyone please tell me: what are the chords in the tailpiece of Dark Blue?
Pretty sure those chords are Db6/9, Gb13, Cm6/9. So, what Maureen said – 9, 11, 13th chords must include the 7th. With the 6 and 9 added but no 7th, it’s called a 6/9 chord.
If anyone’s interested, a simple(ish) way to play a 6/9 chord in RH is to put finger 1 on the 3rd, then stack two 4ths above it.
