Harmonic Series is the music that carried me through this roll in New York. I keep hearing patterns repeat. Glass, steel, branches, spokes, scaffolding. Each a note, each a partial sum. Math and music felt like one thing. And just as there are infinitely many primes, there are infinitely many ways to picture these structures. The beauty is in sensing the hidden rules. The building blocks that shape math, music, the city, and us.
