Oscillators, harmonics, and a way to think of synthesized sound

Have you ever wondered what, specifically, makes a square wave sound different from a triangle wave? Come along for an acoustic exploration of the basic waveforms your synthesizer's oscillator makes and the different harmonic content they represent. Along the way you'll learn about Additive synthesis, and you'll watch me botch an experiment. Fun! Then we'll look at some standard ways to make harmonic content vary over time, and finish up with a working patch. Sine waves, Fourier analysis, dual oscilloscopes - this video has it all! :)
