Keep in mind:
- The rhythm of this exercise is the same as the last one
- It is very important not to pause while switching chords. Instead, continue to strum while you switch chords with your fretting hand. If you're playing with other people, they can't stop while they wait for you to switch chords - you need to learn to keep up.
- If you're having trouble switching chords quickly enough, slow the exercise down, and play it at a tempo that allows you to switch chords without pausing.
- Try playing the exercise alone, and eventually, you can try playing along with the audio example.
