The mathematics of rhythm. The physics of sound. The set theory hidden inside every chord. Explore the connections between music and the disciplines that shape the world.
Explore the DisciplinesFractions govern rhythm. Set theory maps every chord within a scale. Power sets reveal the hidden structure of Western harmony.
View all articles →Sound is vibration. Frequency determines pitch. Amplitude shapes dynamics. Every note is a physics equation in motion.
