Some guitar lessons for beginners may include a lesson on how to read chord charts, but even if your lessons do not you can learn easily by finding a resource online. A chord chart looks like a square filled with grid lines and usually there is a letter printed above the box. This letter, sometimes a letter and a number or two letters, indicates which chord is depicted by the chart. There are five columns within the grid and each vertical dividing line represents one of the six strings of the guitar. Filled-in circles will be printed on various vertical lines, positioned between the horizontal lines - these indicate which frets should be played. Some chord charts may also have open circles positioned above the grid - these indicate that an open string should be played. While it takes time and practice to learn how to play chords, online resources like free guitar lessons and chord charts make it easier for aspiring guitarists to develop their skills. Try out a few different options to discover which works best for you. If you discover that simply practicing your chords is not working for you, you may need to seek additional instruction from a qualified professional or by enrolling in a guitar class.
