Write Two Different Parts of a Song Using The Same Chord Progression

This week's community challenge is simple:
Write two different parts of a song using the same chord progression

It doesn't need to be a full song! Just two sections of something. This is just practice!

Here are a few ways to approach it:

1. Guitar only
Write a progression with a simple strumming pattern, then try a different strumming pattern for the next section OR use different voicings up the neck like in CAGED Basics

2. Guitar and voice
Write a chord progression to use for both parts of the song, but write a unique melody for each section

3. Recording software
You could do all of the above, but with bass, drums, keys, etc. Have one simple section and one filled-out section.
