Pitch is the '''logarithmic''' measure of how "high" or "low" a sound is, which reflects the way human hearing works: instead of hearing absolute frequencies, we instead hear ratios between frequencies. A ratio in frequency corresponds to a simple additive number in pitch. While frequency is measured in Hz (oscillations per second), pitch is measured in logarithmic scales, such as cents. Equal tunings are equally divided in pitch (i.e. 12edo's steps are 1/12 of an octave in pitch, but 2^(1/12) in frequency); the unit of a "cent" corresponds to 1/1200 of an octave, such that the ratio 3/2 is about 702 cents.

'''Pitch''' is the ''logarithmic'' measure of how "high" or "low" a sound is, which reflects the way human hearing works: instead of hearing absolute frequencies, we instead tend to hear [[ratio]]s between [[frequency|frequencies]]. A ratio in frequency corresponds to a simple additive number in pitch. While frequency is measured in {{w|hertz}} (oscillations per second), pitch is measured in logarithmic scales, such as [[2/1|octaves]] and [[cent]]s. [[Equal tuning]]s are equally divided in pitch (e.g. [[12edo]]'s steps are 1/12 of an octave in pitch, but 2<sup>1/12</sup> in frequency); the unit of a cent corresponds to 1/1200 of an octave, such that the ratio [[3/2]] is about 702 cents.
