In an equal temperament, the distance between two adjacent steps of the scale is the same interval in an equal-tempered scale is the ratio:

The physics and psychophysics of the effect are fairly well understood; it occurs when the upper harmonics in the individual voice notes, and the equal-tempered scale.

In 1948 Harry Partch, an American composer, developed a system of music that depended on the building of various exotic instruments that could play non-tempered scales.

He had also been working for a long time on his first theoretical work, " A Theory of Harmony Founded on the Tempered Scale ", published by Novello in 1871.

While technical improvements and an equal-tempered scale reduced the need for two clarinets, the technical difficulty of playing in remote keys persisted, and the A has thus remained a standard orchestral instrument.

17.
That sweeping statement is true : The most common piano tuning, based on what is known as the equal-tempered scale, deliberately alters the pitch of some notes to improve the instrument's overall harmonics.
18.
Some modern instruments play a tempered scale to accommodate fixed pitch instruments such as guitar or keyboard, and are commonly pitched in D . Historical instruments play in a variety of just scales and pitch.
19.
However, unlike earlier 6-or 10-stringed guitars, the normal tuning of the strings Yepes added " also incorporates all the natural resonance that the instrument lacked in eight of twelve notes of the equal tempered scale ".

Here are the sizes of some common intervals in a 24-note equally tempered scale, with the interval names proposed by Alois H�ba ( neutral third, etc . ) and Ivan Wyschnegradsky ( major fourth, etc . ):
