Wow chicka wah-wah

Say “oooh” as in “noodle.” Then say “aaah” as in “park.” When you say “oooh” your mouth is more closed, with less resonating space and a smaller opening. This configuration blocks the higher overtones of your voice. When you say “aaah” your jaw and lips open, creating more resonating space and letting more high overtones through. Now glide from one to the other. The resulting “ooohaaaah” is the sound the wah-wah pedal is named for. By selectively filtering an electronic instrument’s overtones, the pedal can make it sound more vocal. It’s only two vowel sounds out of the dozens your mouth is capable of producing, but it’s a start toward making a more human tone.

Here’s a documentary about the wah:

Tuning the quantum guitar

Music is really just orderly vibrations: in the air, in instrument bodies, in speaker cones, in tiny hairs in your inner ear, in electromagnetic fields in wires, in patterns of neurons firing in your brain. If you understand the math behind these vibrations, it can help you understand how music works. Surprisingly, it can also help you understand quantum mechanics and the fundamental structure of the universe. No joke! Albert Einstein himself used music theory to guide his investigation into the vibrations of the subatomic world. Einstein’s preferred tool for musical investigation was the violin, but any instrument will do.
