Music × Math Lab
From equal temperament to Fourier: hear the math inside a song, then build your own shazam-lite.
Live
- Real problem
- Music isn't decoration for math — frequency, ratio and transforms ARE its skeleton. Let a child enter math through a song they love.
- Math inside
- Equal temperament (2^(1/12) ratios), Fourier transform, clustering
- AI inside
- Four project eggs: shazam-lite (playable demo), audio classifier, mood clustering, tiny neural net
- Story hook
- Your favorite song is a set of numbers that dance.
- Evidence
