About this tuning

Tempered 12-tone scale, an early example of "equal beatingWhen two tones are very close together, they create a rhythmic pulsing related to the difference in frequency between the two tones. The closer the frequencies are to each other, the slower the tempo of the beating.Visit the link to learn more" temperament, in which the wolfA wolf refers to a noticeably out-of-tune interval in a given tuning system that results from adjusting or "tempering" that interval to fit within a fixed number of notes.Visit the link to learn more is divided across two fifthsPitches a fifth apart have a 2:3 frequency ratio (in just intonation) or a difference of 700 cents (in 12 tone equal temperament).Visit the link to learn more, B-F♯ and D♯-B♭.

It can be measured as a ratio between their frequencies or in cents.Visit the link to learn more D-F♯ and the interval F♯-B beat at an equal speed. All other fifths (B♭-B and F♯-D♯) are tuned in 2:3 proportion.
