Explanation

What 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 tip

Aim 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. 1

    Form each shape silently and compare it with the finger chart.

  2. 2

    Play I, I, IV, V at 55 BPM, one chord per click.

  3. 3

    When stable, use two eighth-note strums per click.

Finish this lesson

Mark it complete when you can play three relaxed, clean loops.
