I have a picking pattern for these chords as an intro/verse, but am looking to switch it up with some barre chords for the chorus. Any help would really be nice!

Technically, chords with only 2 notes aren't really chords... But I'll name them for you anyway

First one is just the note C, in an octave. No chord really... You can choose wether you use Cmaj or Cm, or whatever.

Second one is B - C, which could be anything as well... Probably C/B.

Third one is E - C, which could be Cmaj or something.

Last one I would call Gmaj.
