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

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 An overlap between octaves of awareness “In musical tuning, the Pythagorean comma, named after the ancient mathematician and philosopher Pythagoras, is the small interval existing in Pythagorean Pythagoras is attributed with discovering that a string exactly half the length of another will play a pitch that is exactly an octave higher when struck or plucked. 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.

However, Pythagoras’s real goal was to explain the musical scale, not just intervals. To this end, he came up with a very simple process for generating the scale based on intervals, in fact, using just two intervals, the octave and the Perfect Fifth. The method is as follows: we start on any note, in this example we will use D. Dynamiskt Pythagoras träd.

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. 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 -- they are pleasing both to the mind and to the ear. The symbol for the octave is a dot in a circle, the same as for the Pythagorean Monad. In Alchemy this symbol represents gold, the accomplishment of the Great Work .

It was known to Pythagoras that two notes (sounds with different frequencies) sound nice together (harmonious, pleasant) when the ratio of the two frequencies is a simple fraction. For instance, two pitches that are an octave apart have the ratio of 2 to 1 as described above. 2/1 (or its reciprocal ½) is a simple fraction, and these two notes sound nice if played simultaneously.
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. However, Pythagoras’s real goal was to explain the musical scale, not just intervals. To this end, he came up with a very simple process for generating the scale based on intervals, in fact, using just two intervals, the octave and the Perfect Fifth. The method is as follows: we start on any note, in this example we will use D. Non-whole number ratios, on the other hand, tend to give dissonant sounds. 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). Pythagoras (6th century BC) observed that when the blacksmith struck his anvil, different notes were produced according to the weight of the hammer.
Full of the discovery of these simple ratios, Pythagoras set about developing a musical scale, a collection of notes that could be played at different positions on the monochord. Step one was the octave. He drew a line on his monochord under the 1/2 way point, where our 12th fret is today. He wanted the scale to be within the octave.
Pythagoras had many legends told about him.
