I bought a recorder last year and did a few videos of me playing. What a shock it was too
I did'nt realise how much I fidgited and moved about when playing.
However, it was good to watch my fingering and being able to do some adjustment on this matter, plus my timing which to be honest was a bit off at times.
As for the ugly mug, well I've had many decades to get used to looking at that every morning I shave

and not a pretty site, but cant do much about that one I'm afraid.
But the video thing is a great idea I think.
Hugh.
