Guitars can be classified in a few different ways, such as differentiating their construction, playing range or their acoustic/electric quality.

===Construction===

===Construction===

Guitars may be classified as being [[acoustic]], semi-acoustic or [[electric]]. Acoustic guitars are usually made of wood, and produce sound based on the acoustics which resonate through the hollow chamber of the guitar. These guitars can be used in a live performance without amplification due to the resonance and volume the guitar chamber is capable of producing.

Guitars can also be classified according to their range capabilities. Electric guitars have a 4-octave range, while bass guitars have a 3-octave range which is one-octave lower than the electric guitar's range. The range of these guitars may be altered by using guitars with twelve strings. This is commonly known as a doubled six-string guitar, however the second set of strings are tuned to an octave higher than the original strings. Therefore, this would add another octave to the guitar's upper range.

==Tuning==

 

There are many tunings used for the guitar around the world. There is however, a tuning commonly known as "standard tuning", being (low to high) E A D G B E. This tuning has been considered as the standard since the late 18th century.<ref>http://www.guitarnoise.com/faq.php?id=23</ref> There are alternate tunings commonly used, such as drop-D tuning, open-C tuning and open-G tuning. The tuning of the guitar can have a noticeable effect on the timbrel quality of the notes produced.

In standard tuning, the guitar has a usual range of four octaves, ranging from E3 to around E7 (on a 24-fret guitar). This standard range can be broadened by using basic guitar techniques such as bending a note to raise its pitch, or by using a vibrato-arm on an electric guitar to lower its pitch.
