The simplest answer and the one that no student that ever wants to hear is practice. Changing chords is the process where many beginners fail, and quit. But after that, the rewards will be simply impressive. There are a few tricks to get a chord transition to happen faster. Use a metronome: Set it on four beats and set it as fast or as slow as you want. Then get a chord in your mind, say D. When the metronome reaches its last beat, press down the strings. When it happens again, strum it and let it free. Then again. Do this 10 to 20 minutes a day and in less than a week, the chord progression will begin to sound much better.
Manage the finger pain. There'll be a point at which things will seem bleak: you can't quite get to each chord as fast as you want, your fingers are killing you, and it seems easier to put the thing back in its case. The reason most guitar players stop playing a few weeks in is that it hurts. After a couple of months and years of playing, callouses will build up on the fingers of your fretting hand that will greatly reduce the pain of pushing down the strings for long periods of time. Everyone who learns to play the guitar has to deal with sore fingers at the beginning. Learn to love the pain and associate it with everything that you love about music and the guitar.

You can record anything played by this virtual guitar and play it back at will. To start and stop recording check and uncheck the box RECORD. A playback button will appear automatically. You can have many playback buttons: each with its own recording. You can even play back more than one recording at the same time while making another recording to combine them.
The iconic Les Paul Standard is celebrated by the world’s greatest musicians as the standard for perfection in the world of electric guitars. The new Les Paul Standard features the popular asymmetrical SlimTaper neck profile with Ultra-Modern weight relief for increased comfort and playability. Impeccable looks are highlighted by the powerful tonewood combination of mahogany back and carved maple AAA figured top. BurstBucker Pro humbuckers provide modern and classic tones, while immense tonal variety from comes from 4 push-pull knobs. Includes hardshell case.
4.) Check the guitar’s string height by pressing down on the first, second, and third fret. You should be able to do so with minimal effort. Come to the 12th fret and press down. The distance from the top of fret to the bottom of the string should be no more than three times. If it is five times, the guitar may have a warped neck or too high of a bridge.
Hold your guitar correctly. When you are sitting down, there are two main ways to hold your guitar. For a casual playing style, lay the guitar over your dominant leg. On the other hand, the classical method has you set your guitar on your non-dominant leg. In both instances, make sure that the guitar is held close against your body. Holding your guitar properly makes it easier to play and prevents you from becoming fatigued. Play around with both styles and figure out which one is most comfortable for you.[2]
Learn how to read guitar tabs. Guitarists have their own system of music notation called guitar tablature, or guitar tabs for short. The basic idea is to look at each line in the "staff" of the tab in the same way you look at your guitar. Each line corresponds to a string, and each number tells you which fret to hold down when plucking that string. For example, to play this tab-notated lick from the Lynyrd Skynyrd song "Sweet Home Alabama," you would play two notes on the open D string, the B string at the third fret, the G string at the second fret, etc.[10]
Now many people are going to ask about other brands, like why don’t I suggest Gibson guitars? It really is a personal taste thing, and it’ll ultimately depend on yours. Perhaps by the style of music you play or the artists you admire. For me, Fender guitars represent the best in quality and feel. Many Gibson style guitars have fatter necks, bigger frets, are heavy, and feel and sound “muddy” to me, whereas the feel of a Stratocaster– light, slender, classic– feels, plays, and looks fast.  :)
I was lucky enough to meet Justin at the Guitar Institute during a summer school in 2004, and to have some private lessons with him afterwards.  He was the teacher who kickstarted my guitar career and persuaded me that I was ready to join a band.  That was 14 years ago and many dozens of gigs later.  I’m now just finishing a degree in Popular Music Performance.  Justin's online lessons are easy to follow and he has a manner about him which makes you believe that you can achieve.  Where he demonstrates songs, I have found his versions to be consistently more accurate and easy to follow than those of any other online teacher.  On this website you really will find all the skills and information you need to become an excellent musician.  Many thanks. Ian.
String$:  When you're done playing, wipe your strings with a cotton cloth or old T-shirt that's been treated with a small amount of light household oil such as WD-40. This cleans the strings and displaces moisture that can shorten string life. This simple process will extend string life 3 to 4 times compared to untreated strings, saving you money, and giving you more time to spend playing your guitar instead of changing strings.
