Interactive Music Mini-Games
Experience theory by playing with it! Rearrange songs into different styles in real time, challenge your two-handed polyrhythm coordination, test your acoustic ear, and paint modal melodies.
The Physics & Mathematics of Sound
Music is mathematics made audible. Explore standing wave vibrations on strings, wave superposition, acoustic beating, the natural overtone series, and the ancient mathematical dilemma of the Pythagorean Comma.
Scales, Modes & The Geometry of Harmony
Compare the brightness spectrum of Western diatonic modes, spin the interactive Circle of Fifths, explore non-Western microtonal traditions (Chinese Lรผ, Indian Ragas, Arabic Maqamat), and inspect Euler's 2D Tonnetz lattice.
Rhythm, Polyrhythm & Euclidean Geometry
Rhythm is time sculpted by geometry. Discover how Euclid's 2,300-year-old GCD algorithm naturally generates world rhythms, witness synchronized celestial polyrhythm orbits, and adjust the microtiming swing slider.
Timbre, Acoustic Modeling & Harmonics
Why do a violin, a piano, and a flute playing the exact same note sound completely different? Shape custom waveforms with the 16-drawbar Fourier additive synthesizer and test your ears with the blind instrument experiment.
