27.4 · Guitar Chords

Your first loop

In the key of G, the chords G, C, and D are I, IV, and V: home, away, and the pull back home. You can already hold all three shapes. Loop them and you're playing songs.

Three shapes, three jobs

The same chords you met as roman numerals, now as grips. Tap to strum each one.

Loop it

G to C to D and home again. The dots wear the chords' role colors; the voicings are the open shapes you just held.

I, IV, V, I: the loop under thousands of songs.

Add the Em you learned last lesson and this is the pop loop: I, V, vi, IV.

Keep it looping

Want drums and a click under your strumming? Build either loop in the looper and play along.

Open the progression looper, pick the key of G, and tap the same numerals in.
