Question about Accompaniment Playing Study 3, Ex 2.2

Hello David,

In Accompaniment Playing Study 3, Ex 2.2, when playing chord tones, holes 1-6. Hole 6 is G blow and A draw. A is the 9th of the G chord but it doesn't sound right (good to me) when it is played for the G chord.,so I will use G, 6 blow for the G and the C chords, and A, 6 draw for the D.

This Level 3 has not been easy for me; I want to be sure I have the right idea before I submit my effort. Thanks.

Hank
