Question:

"Lucasholland asked "Hey guys, in addition to my other open Q&A I've got another question: When playing (especially on the low E string) should there be a gap between my hand and the neck or is it okay for my hand to touch the neck (and to mute the high E) while doing my exercises on the low E string. I realize that it's not okay for the high E to be muted when you're playing a chord that needs that note but in other situations (like finger exercises) is it okay for that to be the case or is it a bad habit I should correct? Thanks, Lucas.""
