Know-it-all 101 π ➡️ ~ The Invention of Music Theory
Have you ever wondered why music has exactly 12 notes? Why not 13 or some completely different number? As strange as it sounds, the answer goes all the way back to a name you’ve definitely heard before; Pythagoras. Yep, the triangle guy. But he didn’t just obsess over triangles, he basically invented music theory, too. It all started when Pythagoras noticed something odd while listening to a blacksmith at work. As the hammer struck the anvil, it produced a musical note. He realized that using a hammer half the size produced the same note, but in a higher octave. That was his first big insight; octaves aren’t spaced out arithmetically they’re spaced geometrically. In simpler terms, the frequency of a note and its octave follows a 1:2 ratio. Personally, I find it easier to think in solfa notation, so I’ll stick with that for this explanation. Pythagoras kept experimenting. When he used a hammer one-third the size of the original, the new note sounded like a fifth of the higher octav...
