Guitar Strings And Notes

As you learn to play the guitar, you may become curious as to how the various sounds are made. Each string can create a number of different pitches, and there are tricks that can allow a player to extend the range of notes a single string can make.
To learn about the sounds a guitar can make, you must first start by learning the basics ways to change the sounds of the guitar.

The Notes on the Guitar Strings: Six Strings, Six Notes
A typical guitar has six strings, each of which has a different thickness and therefore the ability to play a different set of notes. In “standard” tuning, the guitar strings are tuned (from low to high) at E, A, D, B, G and E.
These notes can be changed by tightening or loosening the tuners at the top of the guitar. Each string tends to be tuned in relation to the string above it, leading to a lower notes being on lower strings and higher notes on the higher strings.
Different styles of play tend to require different types of tuning, so learning how to tune your guitar to a different key is usually a necessity.
Guitar Strings and Notes:  The Frets
Most of the pitch changing on a guitar will take place on the frets. To change the sound of a note, one must firmly hold down the string on one of the frets. Each space raises the pitch of the string by one half step, or half a note.
On low E, for example, pressing the first fret while strumming will change the note to an F. Holding down the frets on multiple strings will help the player to create chords, while holding down multiple frets on a single string will simply do no good.
Guitar Notes Strings: Changing the Sound
There are other ways to change the sound of a string than playing a fret or changing the tuning.
One of the simplest ways is by “bending” the string. While playing, use the finger on the fretboard to bend the string forwards or backwards; this will warp the sound produced and create a rather unique effect.

Many electric guitars allow players to warp the sounds of all strings at once through the use of a whammy bar. This tool bends every string on the guitar, creating a very distinctive distorted sound, as the bar is depressed and released.
