Vibration, oscillation, wave number or frequency shown as a ratio or fraction. For instance, 3:2 also viewed as ^{3}/_{2}.

The vibration ratio or vibration fraction of an interval, is the ratio of the vibrational numbers of the two sounds forming that interval. [This ratio is always proportional.]
