Guitar chords are the basis of thousands of songs. It is more important to know a large number of chords for guitar rather than just learning where the notes are. The chords incorporate the notes into playing. An open chord is one where there is at least one open string played in combination with several non open strings.When learning guitar chords the first thing you are going to want to know is how to read a guitar chord diagram. These are very basic and to the point. The diagram consists of the beginning section of the fret board, usually frets one through five. It would look exactly like if you were staring at the first five frets of a fret board. There are then dots indicated on the diagram to where the fingers are to be placed. This is also very easy to follow once you see the diagram. The only notation you are going to want to know is on some diagrams there is an X or an O. An X indicates that the string is not to be played; an O indicates that it is an open string. Both of these notations are located on top of the diagram right above the string.You will want to familiarize yourself with some of the more popular major and minor open chords. These are the basis of hundreds of songs and just knowing them will allow you to play many of them. Some well known major chords are C, A, E, G, D. Some well known minor chords are Dm, Em, Am, Cm.
When learning to play chords you will want to figure out the positioning of your fingers on the correct strings to make it not only comfortable to play them, but also so they come out clean when you strum the guitar. Learning chords can be difficult at first; especially transitioning from one to the other but with practice you will be able to accomplish it. To make sure they are coming out clean, practice putting your fingers on the chord and playing each note inpidually. If a string is muffled or buzzing practice positioning your fingers in the correct position so that they ring true.
If you have come this far on your journey you are making excellent progress. At this point the more you stick with it and learn the basics of the guitar the more you will become motivated to keep playing. If you are having a difficult time learning this, do not give up! Set a pace for yourself and know that this takes time.
