Pythagoras and 432 Hz

A very peculiar association that I've encountered more than once is with the name of Pythagoras. I was quite surprised to find the note A = 432 Hz addressed as Pythagorean tuning.

Pythagoras is beyond the scope of this article, and discussing Pythagorean tuning would lead us too far astray. However, I would like to point out that none of the historical sources available on this semi-mythical character makes any mention of frequencies of vibration, simply because at that time the assignment of a numerical value representing a periodic frequency had not yet been introduced (as far as we know). Furthermore, all the texts available were written after the lifetime of Pythagoras. We do not possess any written material by Pythagoras himself.

The Pythagorean tuning system is based on a cycle of pure fifths (the 3:2 ratio found in the harmonic series). This tuning is not the one commonly in use today, and one of the reasons why is because a full cycle of 12 fifths should coincide with seven octaves but it actually does not. The difference between the note we land on after stacking 12 fifths and the one we land on after seven octaves is known as the Pythagorean comma (the ratio of 531441:524288).
