2/1 P8 perfect octave C
3/2 P5 perfect 5th G
5/4 M3 major 3rd E
7/4 m7 minor 7th Bb
11/8 P4 perfect 4th F
13/8 m6 minor 6th Ab
17/16 m2 minor 2nd Db
19/16 m3 minor 3rd Eb
23/16 A4 augmented 4th F#
29/16 m7 minor 7th Bb
31/16 P8 perfect octave C
37/32 M2 major 2nd D
41/32 M3 major 3rd E
43/32 P4 perfect 4th F
47/32 P5 perfect 5th G
53/32 M6 major 6th A
