The guitar has six strings, and each string has a name and a number. The names of the strings, listed from low to high, are E, A, D, G, B, and E. The thickest string is the low E string, also known as the 6th string, while the thinnest string is the high E string, also known as the 1st string. To help remember the string names, there are a few sayings that can be used, such as "Eddie Ate Dynamite, Good Bye Eddie" or "Eat A Dead Grasshopper Before Everything". Its important to know the names of the strings to tune the guitar and to identify the notes played on each string.
