The guitar is an ancient musical instrument used in a wide variety of musical styles. Typically it has six strings, but four, seven, eight, ten and even twelve string guitars also exist. Guitars are recognized as the main instrument of different music genres such as, blues, rock, flamenco, and many forms of pop between other genres. Guitars can be divided into two categories primarily by the way the sound is generated. Acoustic guitars produce sounds by the vibration of the strings and the tone is amplified by the hollow body. Electric guitars also produce sounds by the vibration of the strings, but the tone is amplified and electronically manipulated by an amplifier, these electric guitars were introduced in the 20th century and continue to have prominent influence on popular culture.
An acoustic guitar does not dependent on an external device to be herd, but uses a soundboard which is a wooden piece placed on the front of the guitar’s body, this sound board is the part of a string instrument that transmits the vibrations of the strings to the air to be amplified by the hollow body. Acoustic guitars are quieter than other musical instruments commonly found in orchestras and bands, thus when played within these groups they are often externally amplified. Many guitars today are created with internal pickups which enable the player to amplify and modify electronically the raw guitar sound. There are several subcategories within the acoustic guitar group: classical and flamenco guitars; steel string guitars, which include the "folk” guitar; twelve string guitars and the arch top guitar. These types of guitars rely only in the soundboard and the body to be herd, unlike the electric guitars.
Electric guitars are built with a solid, semi hollow or hollow body, they rely on electronic amplification. This guitars use electromagnetic pickups to convert the vibration of the steel strings into electric signals (instead of a soundboard) which are transmitted through a...
