Two tones have a number of tones {interval, music} between them. Interval can be halftone {minor second} or whole tone {major second}.
Interval can be whole tone and halftone {minor third}, with frequency ratio 6:5, or two whole tones {major third}, with frequency ratio 5:4.
Interval can be whole tone and two halftones {diminished fourth, interval}, two whole tones and halftone {perfect fourth, interval}, or three whole tones {augmented fourth, interval}.
Interval can be two whole tones and two halftones {divided fifth}, three whole tones and one halftone {perfect fifth}, with frequency ratio 3:2, or four whole tones {augmented fifth}.
Interval can be three whole tones and two halftones {minor sixth}, with frequency ratio 8:5, or four whole tones and one halftone {major sixth}, with frequency ratio 5:3.
Interval can be three whole tones and three halftones {divided seventh}, four whole tones and two halftones {minor seventh}, or five whole tones and one halftone {major seventh}.
Interval can be five whole tones and two halftones {octave, interval}, so one tone has twice the other's frequency.
