Pythagoras and his followers elaborated this theory to generate a series of musical intervals—the so-called “perfect” intervals of the octave, fifth, fourth, and the second—with whose whole number ratios that could be demonstrated on the string of the monochord.

Pythagorean temperament was historically the first of temperaments using all 12 semitones within the octave. This temperament uses the fifth as the biulding

Being a truth-seeker, Pythagoras traveled to foreign lands. It is presumed he received most of his education in ancient Egypt, the Neo-Babylonian Empire, the Achaemenid Empire, and Crete. Pythagorean tuning is a system of musical tuning in which the frequency ratios of all intervals are based on the ratio 3:2. This ratio, also known as the "pure" perfect fifth, is chosen because it is one of the most consonant and easiest to tune by ear and because of importance attributed to the integer 3. One does not form an octave by reducing the length of on string by a fixed amount, like 10 cm. Rather, one forms an octave by dividing the length of a string by a factor of 2.

The perfect fifth is the first interval to get us into harmony. ~The Circle of fifths~ Pythagoras then realized many things, and also defined exactly what an octave was.

The fourth is ¾, the fifth is 2/3. SC/NATS 1730, V. 8. Two notes that are exactly one octave apart sound good together because their So in order to keep pure octaves, instruments that use Pythagorean tuning Let us next consider a vital melodic interval in our scale: the diatonic semitone or minor second occuring at b-c' and e-f'.

Octave = 2/1; Fifth = 3/2; Fourth = 4/3 (Click here: Pythagoras: Music and Space for an excellent interactive demo with sound.) Pythagoras and his followers regarded this 1-2-3 series as holy - the ancient Greek philosophers were fascinated by numbers, believing that certain numbers, and the relationships between those numbers, had divine Se hela listan på storyofmathematics.com In each frame he sounds the ones marked 8 and 16, an interval of 1:2 called the octave, or diapason. In the lower right, he and Philolaos, another Pythagorean, blow pipes of lengths 8 and 16, again giving the octave, but Pythagoras holds pipes 9 and 12, giving the ratio 3:4, called the fourth or diatesseron while Philolaos holds 4 and 6, giving the ratio 2:3, called the fifth or diapente . Pythagoras also figures in the political history of Greece, because around 531 BC he went into exile, to Italy, to escape the rule of the tyrant Polycrates of Samos. There he became, briefly, a tyrant himself. In the Pythagorean theory of numbers and music, the "Octave=2:1, fifth=3:2, fourth=4:3" [p.230]. A song by my alter ego DJ Impostor.
