I just remembered that last month during February Album Writing Month, I used a capo to let me play in open G with the ringing notes and all in this song:

I think I had the capo on the 5th fret. Open chord shapes used: G, D, C, Em I think that was it. Try playing that with barre chords and get the same kind of jangly tone - just not going to happen.

This was a one mic, one take, little bit of improv on the outro. The LDC mic I was using was sensitive enough to pick up the guitar in a reasonable balance for the demo of the song. I will definitely be working on this one. Moving to Colorado next month and that inspired the lyrics to this song.

Putting the capo on the 5th fret (maybe 4th, I don't really remember) and just messing around with some typical chord shapes inspired the music. I had the thing put together in an hour.

So, chalk that up to another reason to use a capo - it can be inspiring.
