1. Make 2-3 new chord progressions using at least five chords with at least one measure that contains two different chords within it.
2. Make sure to build your chords from the lowest string fretted to the highest string.
3. Practice the note reading exercises for your high E string to a metronome of 60 BPM.
4. Practice both the chords and single notes in small chunks, gradually building out, and using the Rule of Five, where you must complete five reps correctly with no mistakes before moving on to another chunk or adding another element. If you make a mistake on the fourth rep, for example, you have to start over at 0!
