I added this to another similar graphic already. The ninth harmonic is a major twenty-third. Likewise, the fifteenth is much closer to a M7 than the 7th is to a m7. No need for a question mark there. Also, the seventeenth and nineteenth harmonic, while outside the scope of this graphic are also quite in tune with equal temperament. -69.151.147.118 (talk) 23:00, 3 March 2010 (UTC)
