RE: [Harp-L] Numbers Game

[Buck Worley <boogalloo@xxxxxxx>]

A few quick examples:
 
Chord         Formula (From a C Major scale)
 
C2             1, 2, 5 (no 3rd is played)
C9             1, 3, 5, b7, 9
C4              is an explosive :D (however, a Csus4 = 1, 4, 5)
C11            1, 3, 5, b7, 9, 11
Cmaj6        1, 3, 5, 6
C13            1, 3, 5, b7, 9, 13
 
At a glance, your obsevations look fairly sound, however, a 2 note vs a 9th note does not necessarily require an octave of seperation etc. It depends on the voicing or position.
 
Please correct me if I am wrong.
Buck
