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 (lowering the sixth string by a whole tone to D), open-C tuning (CGCGCE) and open-G (DGDGBD) tuning. The tuning of the guitar can have a noticeable effect on the timbral 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.
