What did Pythagoras notice?
What did Pythagoras notice?
Nearly 3000 years ago, Pythagoras walked past a blacksmith where several anvils were being struck by hammers. He noticed that some anvils sounded good together and some did not.
Legend tells us, this was the start of Pythagoras’ investigation into the science of consonance (notes that sound good together) and dissonance (notes that don’t sound good together). This is the science behind how one note can affect, and be affected by, another note.
Pythagoras discovered that certain mathematical proportions equate to certain intervals (distances between notes). In the case of anvils and hammers, it was size and weight that determined the relationship between the notes that were sounded.
The Pythagoras: Music and Space website shows the Pythagorean proportions, with sound clips. When Pythagoras experimented with strings and found that:
A string half the length of another string will produce an interval of an octave A string the length of another string will produce an interval of a fifth
A string 3⁄4 the length of another string will produce an interval of a fourth.
Similarly Harmonics work according to mathematical proportions
When one string vibrates at it’s full length it will resonate it’s key tone.
If a finger is placed half way along the string, it will resonate 1 octave higher.
If a finger is placed at a third it will sound one octave and a fifth higher.
If a finger is placed at one quarter along the string, it will resonate 2 octaves higher.
Try it out! Find a Ukulele or a Guitar or any other string instrument and see if this works!
