	'''Equivalence''' is the phenomenon of psychoacoustics that two notes an [[octave]] apart are considered "(substantially) equivalent" to the brain. The question of whether it can (and should) generalize or generalizes to other intervals is still being studied. This question relates to the height of the interval's denominator in the (odd) harmonic series and another phenomenon presumably of psycho-acoustics that melodies within the range of a tenth are considered to sound "cohesive" or "coherent" to the brain.

This question relates to the height of the interval's denominator in the (odd) harmonic series and another phenomenon presumably of psycho-acoustics that melodies within the range of a tenth are considered to sound "cohesive" or "coherent" to the brain. Equivalences are generally easier to hear for consonant intervals rather than dissonant ones.
