I've put up a video lesson on youtube using John Dowland's little gem "Mrs. Winter's Jump".
The pdf for the music is also available for those who might like to learn it.
I've been meaning to do more videos, but to be honest, I'm not quite comfortable talking to a camera without the interaction of a student, so I tend to find reasons not to do them. I keep telling everyone in my lessons to "keep stepping into the fire" in order to become comfortable with whatever is uncomfortable - knowing that with time the difficulty will get easier. Of course, it's harder for me to notice when I'm avoiding the fire - especially when the mind gives all kinds of "good" reasons not to step into it.
