Here is a guitar lesson I made for the first 9 bars of Moonlight Sonata, by Beethoven - its a dark and moody piece to play, especially outside at night during a full moon!
I made this lesson several years ago, and am still happy with the job I did with it, although I play it a bit more proper these days, and have created a website dedicated to teaching this whole piece on guitar - I still have a 2 or 3 more vids to add until that is complete, but I worked out the guitar TAB transcriptions for the whole piece!
