It is usually called the "interval of equivalence" because tones separated by an octave are perceived to have the same or similar pitch class to the average human listener. The reason for this phenomena is probably due to the strong region of attraction of low [[harmonic entropy]], or the strong amplitude of the second [[harmonic]] in most harmonic instruments. | ||
It has a frequency ratio of 2/1 and a size of 1200 [[cent|cents]]. It is used as the standard of (logarithmic) measurement for all just intervals. | |||
