Bouncing Notes

A simple musical web toy. 

• Click anywhere within the box to create a ball that bounces back and forth horizontally. 
• The slider controls the speed of all balls and can be adjusted by clicking and dragging its node.
• Spacebar to clear the screen of balls.

The ball will play its note when it collides with the edges.
The height of the balls' position determines its note.
