Every note on the guitar has a name, represented by a letter. The names of each of these notes is important; guitarists need to know where to find these notes on their instrument, in order to read music.
The image to the left illustrates the names of the six open strings on the guitar.
The strings, from sixth to first (thickest to thinnest) are named E, A, D, G, B and E again.
In order to help you memorize this, try using the accompanying phrase "Every Adult Dog Growls, Barks, Eats" to keep the order straight.
Try saying the string names out loud, one by one, as you play that string. Then, test yourself by pointing to a random string on your guitar, then trying to name that string as quickly as possible. In following lessons, we'll be learning the names of the notes on various frets on the guitar, but for now, we'll just stick with the open strings.
