Because people learn in a variety of different ways, the flexibility of the online guitar lessons that you choose will be important. You may prefer to progress through a series of programs or you may want to jump around and pick whatever interests you. Not all online guitar lessons work in the same way, so you will want to consider which programs offer the best “fit” for the way you learn best.

The quality of a few older lessons are subpar, they should just remove those or reshoot them. For example, there is a teacher called Hanspeter Kruesi, who seems like a nice guy, presents useful content, but the 360p lessons shot YouTube style at his house in front of his PC don't live up to my expectations. I'm just talking about a few lessons here, but still.
If you already know how to play the guitar or have at least some skills, then you might think that online guitar lessons would be a waste of time. Nothing could be further from the truth. When you take online guitar lessons, especially from a reputable company, you will gain access to some of the world’s best guitar players from whom you can learn a variety of skills and different playing styles.
We were privileged to have worked with hundreds of top artists and educators who authored the original magazine articles and then recorded audio lessons in their own studios. While video is the medium of choice today, these 1,200+ audio lessons still deliver amazing instruction from some of the best in the biz — perfect for those long drives and commutes!

But than again, JamPlay does have a cool scale library tool (which is great for intermediate-advanced players), the production quality of JamPlay videos is generally higher (the educational value is about the same), and they release more new lessons and mini courses in different genres for intermediate-advanced guitarists, which might make them a better choice if you're an established player.
As you can see in our review, offers many lessons on playing the acoustic guitar, and I definitely think it will be of help to you and allow you to advance your playing. I would suggest you sign up and check out the acoustic guitar lessons, and if you aren’t satisfied with them, just ask for your money back within 60 days, GuitarTricks will refund the total amount.

It’s a shame this app with excellent content is almost unusable. The app’s buttons (back button etc) when in a lesson frequently become unresponsive . The video control buttons disappear randomly. And there is no way to play the videos in landscape mode, which is basic stuff! I am using iPhone 6 with latest iOS. All in all the app quality does grave injustice to the awesome content. At the minimum, the unresponsive buttons, disappearing video controls (pause, forward/rewind, no skip back 10 seconds!) and lack of landscape mode video must be fixed on priority. Eventually the app must rewritten by some quality/experienced app developers and experts in mobile app user interface/experience . The great content in the app deserves better software for presenting it! Had it not been for the awesome content, I would have given it 1 star.
Arpeggios are just chords, but how they are played is a special technique unto itself. The left hand playing single notes and the right hand strumming a chord is such a great technique builder. I can’t express enough how important it is to work on these. Combining technical and musical efforts in a logical progression is without a doubt the best way to become a great guitarist.
So, don't get too caught up in strums, as the best approach is to start any new song with this basic down strum. Then, hit the strings on the way up as well, the down-up strum while counting "1 and 2 and 3 and 4 and." This way you are making twice the amount of sound with the same hand motion, giving you a little more movement and fuller accompaniment to a vocal line (melody).
Of course, this top-down lecturing is all very abstract without examples. Let me give you the worst case scenario. My school talent show, 2008. Two friends of mine performED an ambitious but utterly inappropriate Metallica cover in front of the other students, their parents and the faculty. It was excruciating. Although the solos (presumably the only thing they had bothered to practice) were technically flawless, the whole song was undone by their terrible rhythm. The timing of the song became displaced, the chords were so badly fingered that it was difficult to hear the riff and consequently the whole performance fell apart. They looked like morons. They had sacrificed learning basic rhythm and paid the price. Make sure you don’t do the same.
To get good touch in your strumming hand, it’ll take longer than 10 hours. It’s about reps. Try to consider the amount of finesse you are hitting the strings with. Do a little research on palm mutting and other useful strumming techniques. If it sounds nasty at first, that’s cool. Your fingers and wrists will start to adjust. Focus on getting quality sounds out of the guitar.
