A Scaling system where the octave is divided into 12 equal parts. The ratio of the frequencies between any two adjacent notes is exactly the same. Most keyboard instruments are scaled in this manner. Some keyboards can be tuned to other relationships by the use of the tuning function built into them by the manufacturer.

There are many different scaling or tuning systems that define how individual notes are tuned in relation to each other. Equal Temperament is a Scaling system where the octave (see DJzone archive octave) is divided into 12 equal parts. The ratio of the frequencies between any two adjacent notes is exactly the same. Most keyboard instruments are scaled in this manner.

The present system of tuning bells (and other instruments), whereby all half-tones are identical; the octave is divided into 12 divisions of 100 "cents" each.

A technique of adjusting tunings that divides the octave into twelve equal half-steps (in theory, then, each half-step is the twelfth root of 2 above the previous one); it assures that all keys have the same acoustic quality. Equal temperament is more an ideal that something you hear all around you: in practice, especially with non-keyboard instruments and voices, pitch is adjusted in many different ways for all sorts of reasons.

the division of the scale based on an octave that is divided into twelve exactly equal semitones; "equal temperament is the system commonly used in keyboard instruments"

Standard Western tuning that divides an octave into twelve equal parts.

A way of tuning the diatonic scale such that all semitones are identical in size. Allows instruments to play in any key (and bells of a given note to be tuned to the same frequency whatever their position in the peal). Contrast with just tuning and meantone temperament.

The arbitrary division of the octave into twelve equal parts.

Tuning system based on the division of the octave into twelve equal half steps; the normal system used today.

an essential quality for any choirmaster, also describes the Democratic Key System, in which The Distance Between All Semitones Shall Be And Shall Remain Equal And The Same At All Times

a system of tuning wherein the octave is divided into intervals of exactly equal size; twelve-tone equal temperament is the standard system of the Western world.

see scale of equal temperament

Any tuning systemwhich divides the octave into equal intervals.

An equal temperament is a musical temperament, or system of tuning, in which an interval, usually the octave, is divided into a series of equal steps (equal frequency ratios). For modern Western music, the most common tuning system is twelve-tone equal temperament, sometimes abbreviated as 12-TET, which divides the octave into 12 equal parts. This system is usually tuned relative to a standard pitch of 440Hz.
