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.
Minutes 60-600. Pick up the guitar everyday for 20 days for 30 minutes or so. You can do this while you do other things like watch TV or chit chat. Get your fingers used to moving around on the fretboard. Start jamming out some John Denver baby. Please do sing along. Eventually try to keep up with tempo of the changes in the actual song. Once you can change your chords on time, focus on improving your “touch” with your right hand. Strum the chords in a way that it adds texture to the recording (if you are playing along with the man himself.)
Learn how to transition to different chords. One way to become proficient quickly is to learn how to transition between the various chords quickly. These transition periods are often the hardest for beginners to play when they are starting off. The more you practice between switching to different chords, however, the better you'll get at doing it in songs. Practice switching between open chords like G, A, E, and C. 
So you want to learn how to play guitar do you? Well congratulations, because in my ever so humble opinion, learning to play the guitar is among the most rewarding things that you can learn. The goal of this article is not to turn you into some kind of overnight rock star, but rather to give you a bit of an introduction to the guitar, give you a couple chords to work on to get started.
Play the song with the audio recording. Once you've mastered the individual portions of the song, you're ready to play the song in its entirety. Play the song and strum your guitar along with the song. Try to keep up with the tempo of the song you're covering. Follow the tabs as you play. If you mess up, follow the music on the tabs and come back into the song when you're ready. Once you've become proficient at playing the riff, continue practicing until you don't need the tabs anymore.
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.
In 1977, I studied at the Guatemalan National Conservatory of Music with Professors Alejandro Herrera and Rene Abularach on Classical guitar. I also studied harmony and composition with Igor de Gandarias, Juaqin Orellana and Jorge Sarmientos. In New Orleans, I took private jazz guitar courses with steve Masakowski and Hank Mackie. In 1983 I started my own Jazz band, “Acoustic Ensamble”, a band that I shared with well known international musicians like: Carlos Gomes, Fernando Perez, Bryon Sosa, Miguel Angel Villagran, Igor Sarmientos, Alfredo Caceres, Antonio Cosenza, German Giordano, Rolando Gudiel, Roberto Abularach, Auri Ruiz, M ...

Try out different strumming patterns and rhythms. Once you're able to produce a good sounding chord, try strumming it at different tempos and rhythms. Rhythm is based on your strumming pattern, and how long you're holding your notes. Try a basic 1-2-3-4 beat, otherwise known as a 4/4. The number on the top represents how many beats there are in the measure. Try strumming up and down in different progressions to create a different sound for your rhythm. Once you get a basic rhythm down, you can start to incorporate quicker or slower strumming.
Okay, so if the diagram had O’s across the whole thing, then you wouldn’t even have to touch the fretboard at all, you would just strum it. However, this diagram has a couple of other marks on it, and those indicate where we need to place our fingers. In this case, they are on the 2nd fret of the 4th and 5th strings. The frets are the metal parts running perpendicular to your fretboard; they are what the string makes contact with when you press your fingers down. On the diagram, the frets are the horizontal lines. So count up to the second fret, and put your fingers down just behind the fret, like in the diagram.
