What you are playing
Chords for I Don't Know, laid out across its 2:39 exactly where they fall. Most of it sits in D major. It leans on barre chords — with a capo on fret 2 the same song becomes C Am Em G D Dm F, which sits easier under the hand. Every one of its 7 chords is a plain triad, so three notes under the right hand covers the whole song.

On a guitar there is a shortcut in one direction: transpose down by n and put a capo on fret n, and you are back at the original pitch while playing the easier shapes. That is what the capo line above is doing.
