A Sound Visualizer listens to sound or music and reacts by drawing graphics on the screen. Scratch uses the "loudness" block to detect the volume of sound. * You can clap your hands or make other noises to affect the screen graphics. This project plays "The Minute Waltz" by Chopin. The project then listens to the music through your computer's microphone (if it has one) and varies the images on the screen according to the volume. If your device does not have a microphone then default sound levels will be used. Made for the Sound Visualizers studio https://scratch.mit.edu/studios/4132969/
