Bach expected one special temperament to his 24 Preluds and Fugues, and show it at the first page in arabesque. That was not equal temperament as is generally known at present, but the classic unequal one. As an applicant to Leipzig st. Thomas Church's Cantor he submitted to the authorities 24 Preluds and Fugues which were based on the new idea using every 24 tonality in one collective work. It was the breaktrough of the old barock tonal world.In order to avoid low evaluation of the authorities through unpleasant sound and beat caused by unappropriate old temperament and to make the best harmonc effect. Bach manifested the temperament on which 24 major and minor tonalties prtfectly sound. And the authorities in Leipzig did never know it.On the first page of the composition Bach proposed to cembalist in Leipzig how to tune the instrument dealing with beats and sorting 12 perfect fifths into three stages.
