App Description

Listen to the Music of the Polygons...

A bouncing ball makes a sound every time it hits a side of a polygon.

Ramp the beat up to hundreds of beats per minute or slow it down to produce pleasing ambient soundscapes. Faster tempos create lots of energy, even Joy!

Use gestures to control the tempo and the starting angle of the ball. The resulting "flow" has practically unlimited variation. Sound Patterns can be highly regular or very complex.

In one mode, real piano notes are used. In 'Synth' mode, sides have harmonic fractional synthetic tones. See our website for some jazz lessons.

This Elementary Edition of PolygonJazz retains the state of each polygon, but doesn't save polygon songs. (PolygonFlux has an Album of Fluxes).

Play with a Triangle, Square, Pentagon, Hexagon, Heptagon, Octagon, or Dodecagon.

Technically speaking, PolygonJazz generates arpeggios and other musical sequences using the geodesic flow inside a regular polygon.  Our app PolygonFlux fully explores the geometry of "Polygon Billiards".

Each polygon is a dynamic combination of Geometry and Sound you have to see and hear to believe!
