What happens when the 3/2 rhythm is increased in speed until it sounds like pitch? You get the perfect fifth interval as depicted in this experimental musical demonstration. What is pitch? Is it really fast rhythm? What is rhythm? Is it really slow pitch? It is both of these things and fascinating. A perfect fifth interval of two music notes is also a simple 3/2 mathematical ratio.The 3/2 ratio is also a basic poly-rhythm. (Only the 2/1 ratio, the octave in pitch, is simpler.) This experiment uses 2 sawtooth waves sped up over 10 minutes to show the relationship of rhythm and pitch in the music world. Finding a way to increase the speed in a smooth and consistent manner involved experimenting with various techniques until one worked in a relatively glitch free manner over the entire rhythm and human hearing spectrum. I hope the music theorists and audio nerds enjoy this study in sound. Thanks for listening. Dale
