Recently, I tuned my guitar's four low string like a Cello (I kept the G, tuned D to C, A to F and E to B-flat) and added a Capo on 2nd fret. It really sounded amazing (When I Capo-ed it, it really gave me a Cello tuning). So, I decided to record this piece. I don't think I make my guitar a Cello again, but I think it's cool to give it try, at least once!
