d-drop
Drop D is the worst tuning ever, but it’s super popular. It’s like tuning your guitar so it can barely play anything but power chords.
I use drop D because I can’t play anything else. It’s so easy.
My band uses drop D so we don’t have to actually practice. It’s the worst.
I tuned my guitar to drop D so I could sound like I know what I’m doing. I don’t.
