ExplanationWhat this develops
The I, IV, and V are the three essential major chords in a key. Thousands of songs are built from these three sounds.
Move fingers as a small group. The goal is not to place every finger instantly—it is to make the next strum land on time.
Coach's tipAim to have the lowest-pitched fretted note ready first; the pick reaches it before the higher courses.
Practice plan
Take it to the instrument
- 1
Form each shape silently and compare it with the finger chart.
- 2
Play I, I, IV, V at 55 BPM, one chord per click.
- 3
When stable, use two eighth-note strums per click.
Finish this lesson
