Synthesizers are a very recent invention, especially when you compare them to acoustic instruments, like pianos and guitars.

In this episode, we learn how these machines with keys, knobs, switches, buttons and sliders actually make sound. We’ll also travel back to the 1960’s and hear how synth pioneers like Bob Moog helped bring these sound making devices into the mainstream.
