Hi @sticktothemuse thanks for the comments! It too me a while to warm up to using a capo. I’ve been playing for about 20 months and pretty much avoided using one for about 4-6 months as I felt I needed to really figure out the open chord and bar chord shapes first. As I found out though (as you did with Wonderwall), a huge number of songs are actually written with a Capo. Lots of Oasis, The Smiths, and Paul Simon songs use a capo in the studio version. I’m not in any way an expert but to me a capo is a great way of changing the key of the song to make it higher or lower pitched. Also allows you to use the same open chord shapes in different locations on the fretboard so you can get different chord voicings without having to use bar chords.
Justin has some really great explainer videos on how to start using a capo. Which you may have already found since it took me 5 days to respond to your note!
