equaltempered : A system of tuning in which the diatonic comma is divided equally between the twelve halfsteps of the octave. All the halfsteps are equal in size and are exactly onetwelfth of an octave, spanning a frequency ratio of , or about 6%, or 1:1.059. In equal temperament, all the intervals are the same regardless of the key in which one is playing, and none except the octave is perfectly tuned. This makes it very easy to modulate from one key to another, although the keys lose their individuality because they all have equal intervals. The result is that the fourth and fifths are within 0.001% of just intervals, however the thirds are about 0.01% away from pure thirds which produce audible beats, the thirds in all keys being equally bad. See temperament, syntonic comma, diatonic comma.
