The sound that was produced was the same, but more acute (because it was the same note one octave above): Pythagoras didn’t stop there.
He decided to experience how it would be the sound if the string was divided in 3 parts: He noticed that a new sound appeared; different from the previous one.
This note had a pleasant harmony with G and also with C.
This procedure was then repeated starting in D, resulting in A. When they repeated this procedure of dividing the string in three parts once again, resulting in B, there was a problem, because B didn’t fit well when played with C (the first note of the experiment).
In the course of time, the notes were receiving the names we know today.
Many peoples and cultures created their own music scales.
One example is the Chinese people, which began with the idea of Pythagoras (using strings).
They played C in a stretched string and then divided this string in 3 parts, like we showed before. Noticing that these notes had a harmony; they repeated the procedure starting in G, dividing again this string in 3 parts, resulting the note D.
These notes served as base to Chinese Music, making a scale with 5 notes ().
This Pentatonic Scale, for being pleasant and consonant, represented very well the Oriental Culture, which was always connected to harmony and stability.
