Pretty much as the question is asked. I've gotten my E shape barre chord down with no problem on a standard 6 string. But I normally play and practice on my 7 string (tuned to Drop A so I have E standard on the top 6 strings). How do I properly do a barre chord? Do I fret across the 6 and mute the 7th with the tip of my finger, or do I reach my index finger over the 7th and mute it? There aren't a lot of resources out there haha
