Questions about the I–IV–I–V progression

Why does the I chord appear twice?

Because the progression is built in two-bar pairs: I–IV, then I–V. Each pair starts from home, so the ear always knows where the tonic is. That stability is why the shape works for verses that need to sit still while the story unfolds.

What is the difference between 1-4-1-5 and 1-4-5?

1-4-5 moves through all three chords once and cadences. 1-4-1-5 goes back to the tonic between the IV and the V, splitting the progression into two short phrases. The result is more symmetrical and more static — a pattern to repeat rather than a line to resolve.

What strumming pattern fits this progression?

The boom-chuck: play the bass note of the chord on beat one, strum the rest on beat two, an alternate bass note on beat three, strum on beat four. On G that alternates the low G and the open D string; the bass alternation is as much a part of the sound as the chords.
