Watch the Alternating Lead and Rhythm online guitar lesson by Dave Celentano from Classical Concepts for Rock Guitar

I took a few liberties with the introduction (first seven measures) of "Toccata and Fugue" by adding in the A5 and D5 power chord chunks between the actual higher melody of the tune. The two chords aren't played in the original score, but are implied by the notes of the melody and I thought they gave the tune a heavier vibe, so I added them in. With these power chords included, the intro makes a great exercise for alternating rapidly back and forth between lead guitar and rhythm guitar. Switching back and forth between lead and rhythm should be done seemlessly and efficiently, without breaking the beat and the moves should be rehearsed slow enough to appear effortless. If you happen to be the sole guitarist in your band, then you're probably accustomed to wearing lead and rhythm guitar hats.
