Bounce Metronome is a highly versatile rhythm tool designed by Robert Walker, specifically optimized to make complex timing patterns like polyrhythms intuitive to learn. While most standard metronomes only provide an audio tick, Bounce Metronome utilizes a unique “Gravity Bounce” visual interface to remove the guesswork from cross-rhythms.
The application is primarily available as a comprehensive desktop software for Windows (and Linux via WINE), alongside a simplified, free online browser version. Key Features for Polyrhythm Training 1. The Gravity Bounce Visuals
Anticipatory Motion: The app animates bouncing balls that move with natural gravitational acceleration. Because the human brain can naturally predict exactly when a bouncing ball will strike the ground, you can visualize the exact micro-moment a beat will land before it plays.
Conductor-Like Feedback: It effectively simulates the rise-and-fall rhythm of a physical conductor’s baton, making complex, asynchronous patterns instantly readable. 2. Advanced Polyrhythmic Mapping
Massive Layering: The Pro version allows you to layer up to 16 different rhythms simultaneously. Each individual layer can be customized with its own distinct number of beats and subdivisions.
Rare & Mathematical Rhythms: Beyond standard 3:2 or 4:3 polyrhythms, it easily calculates highly complex patterns, including Indian rhythm cycles, irrational meters (e.g., π/4), and the Golden Ratio polytempi.
Polymeters and Cross-Tempos: It manages complex setups like ⁄4 : ⁄3, where two separate time signatures play simultaneously at entirely different tempos. 3. Deep Audio Customization
Stereo Panning: You can pan conflicting rhythm layers to separate audio channels (e.g., Layer A in the left ear, Layer B in the right ear). This isolates the rhythms audio-spatially to help your brain process limb independence.
Harmonic Polyrhythms: A unique feature binds pitch to rhythm. It plays polyrhythmic frequencies using pitch ratios derived from the harmonic series (for instance, a 5:3 polyrhythm played as the pure pitch harmonics of a major chord). 4.
