When was 12 tone equal temperament invented?

While China had previously come up with approximations for 12-TET, Zhu Zaiyu was the first person to mathematically solve twelve-tone equal temperament, which he described in his Fusion of Music and Calendar 律暦融通 in 1580 and Complete Compendium of Music and Pitch (Yuelü quan shu 樂律全書) in 1584.

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").

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.
