What is 12edo?
12 equal divisions of the octave (12edo), or 12(-tone) equal temperament (12tet, 12et) when viewed from a regular temperament perspective, is the predominating tuning system in the world today.
What is the tempered scale?
The equal tempered scale is the common musical scale used at present, used for the tuning of pianos and other instruments of relatively fixed scale. It divides the octave into 12 equal semitones. It is common practice to state musical intervals in cents, where 100¢ is defined as one equal tempered semitone.
Who invented 12-Tet?
Simon Stevin
Simon Stevin was the first to develop 12-TET based on the twelfth root of two, which he described in Van De Spiegheling der singconst (ca. 1605), published posthumously nearly three centuries later in 1884.
What does Edo stand for in music?
In music, 19 equal temperament, called 19 TET, 19 EDO (“Equal Division of the Octave”), or 19 ET, is the tempered scale derived by dividing the octave into 19 equal steps (equal frequency ratios).
What is Edo tuning?
An equal division of the octave (EDO or edo) is a tuning obtained by dividing the octave in a certain number of equal steps. This means that the interval between any two consecutive pitches is identical. A tuning with n equal divisions of the octave is usually called “n-edo” (“n-EDO”).
Why are pianos equal temperament?
Modern Pianos are all tuned using a system called “Equal Temperament”. In fact, you can’t use your ear to tune a Piano in equal temperament because our ears don’t hear notes in this manner. Piano tuners use a device and they need to know how much each note needs to be “out of tune” in order to tune a Piano.
Are piano tuning to equal temperament?
Pianos today are tuned in “equal temperament,” which means that each note is the same distance in pitch from its neighbours.
What is a 12 tone equal tempered scale?
Twelve-tone equal temperament is the musical system that divides the octave into 12 parts, all of which are equally tempered (equally spaced) on a logarithmic scale, with a ratio equal to the 12th root of 2 ( 12√2 ≈ 1.05946).
Who invented tempered tuning?
Their solution, laid out by Pietro Aron in the early 16th century, and referred to as meantone temperament (or quarter-comma meantone temperament), was to temper the interval of a perfect fifth slightly narrower than in just intonation, and then proceed much like Pythagorean tuning, but using this tempered fifth …
How many notes are there in the 31-ET scale?
The following are the 31 notes in the scale: The five “double flat” notes and five “double sharp” notes may be replaced by half sharps and half flats, similar to the quarter tone system: Many chords of 31-ET are discussed in the article on septimal meantone temperament.
How many keys are on a 31tet keyboard?

What is 31 equal temperament tuning system?
The 31 equal temperament has a very close fit to the 7:6, 8:7, and 7:5 ratios, which have no approximate fits in 12 equal temperament and only poor fits in 19 equal temperament. The composer Joel Mandelbaum (born 1932) used this tuning system specifically because of its good matches to the 7th and 11th partials in the harmonic series.
