Watch the Badinerie online guitar lesson by Tony Smotherman from Classical Flatpicking Explorations
You'll see right at the start that Bach is making use of working through the B minor arpeggio in segments. The theme reoccurs several times, the first time in B minor and the second in D minor. A brilliant modulation to the minor third to D minor and the Baroque feel is really evident. This piece is great for alternate picking, developing your knowledge of arpeggio positions, as well as the proper fingerings. A great solo piece that's really musical too.
