It is useful for the tuning of your guitar.
The notes played by the open strings
of a guitar
tuned in ' STANDARD TUNING ' where the A string vibrates 440 times per second are as follows.
(there are other tunings possible which we won't go into here) .
* E Bottom or low E this is the thickest string.
* A = 440 vibrations per second.
* E Top or high E this is the thinnest string.
Sometimes one of the confusions for the novice player, is the fact that ' BOTTOM ' E - is the string which is at the ' TOP ' of the guitar, when the instrument is held in a playing position. What they are referring to, is the fact that this the string which is ' LOWEST IN PITCH.'
' TOP ' E which is the thinnest string, situated at the ' BOTTOM ' of the guitar when held in the playing position, is the ' HIGHEST IN PITCH
The other common method of identifying strings is numerically.
* E - 6th ... Bottom or Low E
* A - 5th
* D - 4th
* B - 2nd
* E - 1st ... Top or High E
The strings are numbered
from the thinnest through to the thickest ' Top or High E = 1st String ' and ' Low or Bottom E = 6th String '
