The extremes of the meantone systems encountered in historical practice are the Pythagorean tuning, where the whole tone corresponds to 9:8, i.e. (3:2) 2 / 2 , the mean of the major third (3:2) 4 / 4 , and the fifth (3:2) is not tempered; and the 1 ⁄ 3-comma meantone, where the fifth is tempered to the extent that three ...
Pythagorean perfect fifth on C Play ⓘ: C-G (3/2 ÷ 1/1 = 3/2). In musical tuning theory, a Pythagorean interval is a musical interval with a frequency ratio equal to a power of two divided by a power of three, or vice versa . [ 1 ]
In music, an interval ratio is a ratio of the frequencies of the pitches in a musical interval. For example, a just perfect fifth (for example C to G) is 3:2 (Play ⓘ), 1.5, and may be approximated by an equal tempered perfect fifth (Play ⓘ) which is 2 7/12 (about 1.498).
12-tone Pythagorean temperament is based on a sequence of perfect fifths, each tuned in the ratio 3:2, the next simplest ratio after 2:1 (the octave). Starting from D for example ( D-based tuning), six other notes are produced by moving six times a ratio 3:2 up, and the remaining ones by moving the same ratio down:
The prime factors of the just interval 81 / 80 known as the syntonic comma can be separated out and reconstituted into various sequences of two or more intervals that arrive at the comma, such as 81 / 1 × 1 / 80 or (fully expanded and sorted by prime) 3 × 3 × 3 × 3 / 2 × 2 × 2 × 2 × 5 .
10, 9, 8, 7, 6, 5, 4, 3, 2, 1 is the fourth studio album by Midnight Oil, released in 1982 by Columbia Records. It hit number 3 on the Australian Kent Music Report Albums Chart during 171 total weeks. [1] The band's first US release, it peaked at number 178 on the Billboard 200. At the Countdown Music Awards, it was nominated for Best ...
Just major third. Pythagorean major third, i.e. a ditone Comparison, in cents, of intervals at or near a major third Harmonic series, partials 1–5, numbered Play ⓘ.. In music theory, a third is a musical interval encompassing three staff positions (see Interval number for more details), and the major third (Play ⓘ) is a third spanning four half steps or two whole steps.

An octave—two notes that have a frequency ratio of 2:1—spans twelve semitones and therefore 1200 cents. The ratio of frequencies one cent apart is precisely equal to 2 1 ⁄ 1200 = 1200 √ 2, the 1200th root of 2, which is approximately 1.000 577 7895. Thus, raising a frequency by one cent corresponds to multiplying the original frequency ...
