THE ACCELERANDO ILLUSION
The Accelerando Illusion is an original musical illusion implying an endlessly rising tempo. Try clapping along! A steady whole-note clap morphs into a half-note pulse, then quarter-notes, eighth-notes and soon you are at the limit of how fast your hands can clap...yet the music sounds the same as when you started!
Make sure you warm up; the tempo starts at a moderate 115 beats per minute, but ends with BPM somewhere in the region of 100 quintillion!
