This classical guitar lesson in right hand articulation is brought to you by Strings By Mail and Gohar Vardanyan. It has an excellent discussion about how to play legato, staccato, detached, and general articulation. I like the two different camera angles as well. If you’re looking for a technique book you can check out my review of classical guitar technique and exercise books.
