Online tone generators are free, user friendly, and can make for engaging and meaningful study of many topics in the areas of interference, waves, and the physics of music. By using a website such as OnlineToneGenerator.com, and through opening multiple windows simultaneously, students can immediately perform several experiments. In this article, I highlight five lesson ideas that come naturally from these types of websites.

Topics
Musical note, Musical instruments, Auditory system, Timbre, Acoustic waves, Oscilloscopes, Wave forms, Signal processing, Fourier analysis, Educational assessment
