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 ratios between frequencies. A ratio in frequency corresponds to a simple additive number in pitch. While frequency is measured in hertz (oscillations per second), pitch is measured in logarithmic scales, such as octaves and cents. Equal tunings are equally divided in pitch (e.g. 12edo's steps are 1/12 of an octave in pitch, but 21/12 in frequency); the unit of a cent corresponds to 1/1200 of an octave, such that the ratio 3/2 is about 702 cents.
