# The resulting scale divides the octave with intervals of "Tones" (a ratio of 9/8) and "Hemitones" (a ratio of 256/243). Here is a table for a C scale based on this scheme. The intervals between all the adjacent notes are "Tones" except between E and F, and between B and C which are "Hemitones."

Pythagoras thereupon discovered that the first and fourth strings when sounded together produced the harmonic interval of the octave, for doubling the weight

Split a string into thirds and you raise the pitch an octave and a fifth. Spilt it into fourths and you go even higher – you get the idea. Pythagoras was looking for mathematical relationships between the most harmonious of notes. He made some discoveries. The most harmonious note came from pressing the string in the middle. That is, when the ratio of the full string to the shortened section was 2:1.

The intervals between all the adjacent notes are "Tones" except between E and F, and between B and C which are "Hemitones." Pythagoras taught that man and the universe were both made in the image of God and that because of this, each allowed understanding of the other. There was the macrocosm (Universe) and the microcosm (Man); the big and the little universe; the Grand Man and the Man. Pythagoras believed that all aspects of the universe were living things.

The symbol for the octave is a dot in a circle, the same as for the Pythagorean Monad.

## The most prominent interval that Pythagoras observed highlights the universality of his findings. The ratio of 2:1 is known as the octave (8 tones apart within a musical scale). When the frequency of one tone is twice the rate of another, the first tone is said to be an octave higher than the second tone, yet interestingly the tones are often perceived as being almost identical.

Pythagoras thereupon discovered that the first and fourth strings when sounded together produced the harmonic interval of the octave, for doubling the weight had the same effect as halving the string. The tension of the first string being twice that of the fourth string, their ratio was said to be 2:1, or duple.

### Pythagorean Scale. Around 500 BC Pythagoras studied the musical scale and the ratios between the lengths of vibrating strings needed to produce them. Since the string length (for equal tension) depends on 1/frequency, those ratios also provide a relationship between the frequencies of the notes. He developed what may be the first completely mathematically based scale which resulted by considering intervals of the octave (a factor of 2 in frequency) and intervals of fifths (a factor of 3/2 in

In this way, Pythagoras described the first four overtones which create the common intervals which have become the primary building blocks of musical harmony: the octave (1:1), the perfect fifth (3:2), the perfect fourth (4:3) and the major third (5:4).

· Thus concludes that the fifth mathematical ratio is 3 to 2. · Thus concludes that the fourth mathematical
In the Pythagorean theory of numbers and music, the "Octave=2:1, fifth=3:2, fourth=4:3" [p.230]. These ratios harmonize, not only mathematically but musically
22 Jul 2019 So a pure fifth will have a frequency ratio of exactly 3:2. Using a series of perfect fifths (and assuming perfect octaves, too, so that you are filling in
Octave as 2:1 (or in Pythagorean terms, 12:6). The octave, 2:1, is of course the most basic ratio, or relationship, in music.

### Pythagoras discovered the mathematics in music. By dividing a string into sections, so lengths have the ratios of 2:1, 3:2, 4:3, or 5:4 (octave, fifth, fourth, third),

### octave, an action not easily condoned at the time, as Greek society held the number seven as sacred, and the addition of the octave disturbed the symbolism of the modes and the seven planets. However, Pythagoras’s standing in the community and in the minds of his followers neutralized any censure that might have ensued.9

Notice that a sequence of five consecutive upper 3:2 fifths based on C4, and one lower 3:2 fifth, produces a seven-tone scale, as shown in Fig. 2. Pythagoras thereupon discovered that the first and fourth strings when sounded together produced the harmonic interval of the octave, for doubling the weight had the same effect as halving the string. The tension of the first string being twice that of the fourth string, their ratio was said to be 2:1, or duple. The Perfect Octave Creates Harmonia Working with his seven-stringed lyre, and thinking of the divisions of the strings that he had discovered, Pythagoras realized that for the relationships to be complete and balanced, the perfect interval of an octave (e.g., C1-C2) must be part of the existing scale. The most prominent interval that Pythagoras observed highlights the universality of his findings.
