There are lots of awesome videos on youtube on how to play the guitar. I would also recommend buying some books on how to play guitar. If you can afford lessons I say go for it. Now when learning to play guitar you are going to need various accessories. I would suggest good strings and plenty of guitar picks. Another important item would be an excellent guitar tuner. Yes you can learn to tune the guitar by the strings. I would buy an electronic guitar tuner, which will make it much easier to tune your guitar. Start playing the guitar today and have fun.
