I need to learn, basically from the start! Anyone know of any good sites that teach it?
I learned completely from scratch using youtube! There are so many good tutors on there. I began using a channel called beefcakejcc which has some excellent beginner scales on there. If you do a search for "beginner guitar tutorials" you’ll find plenty of good lessons.
You can find all your chords on http://www.all-guitar-chords.com.
As for other youtube tutors, once you get more confident with chords, I would recommend Wayslinn, Tbonewilson and Guitartutee (who has a massive range of songs but isn’t as helpful as the others). Wayslinn is probably the most helpful because she explains exactly where to place your fingers for each chord and even gives you detailed strumming patterns. It does depend what kind of music you want to learn though.
Free and Easy guitar also has some excellent tutorials but learn all the basic chords first.
