Hi,
There are some players who are confuse with the 9th chord and I hope to explain clearly here.
The notes in a C major scale are - C D E F G A B C ( 1 2 3 4 5 6 7 8(1) )
The notes in a Cmaj 7 chord are - C E G B (1 3 5 7)
The notes in a C7 chord are - C E G Bb (1 3 5 b7)
To play a 9th chord, it is simple.
For a Cmaj 9, the notes are - C E G B D (2+7 =9)
For a C9 , the notes are - C E G Bb D
So do not mix up Cmaj9 and C9.
Hope this helps.
Cheers
