How to build a whole tone scale and exploring some of its uses. Most musicians are familiar with major and minor scales but what about other scales? The whole tone scale was much used by Debussy and other composers, and it generates a...

The equations for the harmonic frequencies of open and closed pipe wind instruments are derived. An animation of a longitudinal standing wave pattern in a closed pipe is shown. Displacement and pressure nodes and antinodes are shown.

Bo teaches us about beat frequency. You get to hear what beats sound like, see the constructive and destructive interference wave forms, and learn a practical application of beats while tuning a guitar.

Not all waves travel across the ocean or across the universe. Some are stuck in a certain spot! Like the vibrations of the strings on a guitar. What's the deal with these standing waves? And what's this, quantization? Oh my! We'd better...
