Here are some more variations on the rhythmic pattern of this section. These are based on the same harmonic principle - only what used to be played on the bass side is now being played on the treble side and vice versa.
We start out with a simple single note pattern.
Next, the treble line is played in stacked fourths rather than single notes. Remember, this used to be our bass line in previous exercises.
Finally we add stacked fourths on the bottom and get a busy, thick chordal rhythm. Of course you can try other chord voicings although fourths are the most convenient to finger on a Stick.
