Dueling Keyboards
summary
Compares musical and computer keyboards by showing which exact ratios and tunings get built into keys and why that matters for harmony, including live sine‑wave and organ demos and concrete tuning math. Demonstrates Pythagorean tuning, meantone and equal temperament and gives the exact awkward factor Pythagorean comma = 3^12 / 2^19 ≈ 1.01364. Shows code generation of music with Closure, measuring compressibility (Closure example: 15 symbols → 2,001 notes; another 347 → ~3,000 notes), and maps QWERTY input to algorithmic, repeatable musical output.
