This page is designed to test the timing accuracy of the HTML5 WindowTimers.setInterval() method.
Is the timing stable enough to play a rhythm with acceptable accuracy? You be the judge.

The script in this window plays a sequence of pitches in a loop at a rate of 125ms per note.
Does it sound steady? Does it stay steady even when you do other things in your browser?
