Musical interlude

The origins of both Muzak and Sirius?






This is the origin of the principle of the tone generator in my old Hammond organ, I guess.

Found at 2D Goggles.  Thanks to Roberta for finding that in the first place.

Correction - not quite the same as the Hammond - http://magneticmusic.ws/mmalternators.PDF
