this is probably the best i've seen someone describe the basics of FM synthesis. i can't say i've ever used it beyond playing around with presets but i'm inspired to have a tweak now. the dude's monotone voice kinda freaks me out though...

^ Nice find WF, yep he's a bit creepy but he definitely makes good sense.

I'd add for anyone wanting to hear FM at work, slow and simple, try good old Subtractor in Reason.

It lets you assign LFO 1 to 'FM' and then has the FM knob near oscillator 1.

For a good sense of shifting from 'Vibrato' to 'FM' as shown in the video above, set the FM knob to about 12 o'clock or more.

Then assign LFO 1 to FM. Set the 'amount' knob to about 12 o'clock or more (for obvious effect - you can change to make more subtle later). Then set the 'rate' knob to a slow setting.

Play a note and you should hear a deep, slow vibrato. Slowly increase the LFO rate - at some point it will transition from very fast vibrato into a new sounding tone - voila you are hearing FM :(
