I've been meaning to do a complete tutorial on this for a long time! It's finally published.

Muting is a vital technique that is not mentioned as often as it should be. It's implied in almost everything you play on the guitar, from beginner to intermediate to advanced. But it's not always explicitly mentioned.

So, in this tutorial I tried to address the basic principles of muting. The sooner you intentionally incorporate these techniques into your playing, the better you'll sound & the more you'll enjoy playing!
