The octave 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 phenomenon 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. | The octave 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.

An article in ''Current Biology'' shows that octave equivalence might be a cultural phenomenon, it also includes an 8-minute video. <ref>[https://www.cell.com/current-biology/fulltext/S0960-9822(19)31036-X?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS096098221931036X%3Fshowall%3Dtrue Universal and Non-universal Features of Musical Pitch Perception Revealed by Singing: Current Biology]</ref> | |||
