Guitars have played an important part in molding the music of many cultures. Different types of guitars, including acoustic guitars, are used to create certain sounds and styles. Acoustic guitars got their name from the type of amplification they provide. Unlike the electric guitar, they do not need external devices for amplification; they are amplified acoustically. Acoustic guitars generally feature a standard array of six strings, although twelve string ones are also available. Wood is the most commonly used material for making acoustic guitars.

The type of wood used to manufacture acoustic guitars affects the quality and sound of the guitar. Some of them, however, can be made of several other materials. The more expensive guitars are generally made of solid wood tops, sides and backs. Beginner guitars are usually constructed with layers of wood pressed together, though, which is known as laminated wood. Different types of acoustic guitars are classified according to the material used in making their strings.

Nylon is commonly used, but steel string acoustic guitars are sometimes preferred because they can produce a louder sound. Guitars featuring steel strings require stronger construction than nylon string guitars, though. This is because there is a higher tension in steel strings. The body of a steel string acoustic guitar is also larger than nylon string guitars. The size and shape of acoustic guitars dates back to the mid 1800s, and these dimensions remain the same to this day. An acoustic guitar can be used either for finger picking, or for strumming. Regardless of the chosen method of playing, a pick is generally used. The acoustic guitar is used in many styles of rock music, such as folk, country, blues, bluegrass and folk. These guitars are also popular for solo performances. They are perhaps the most diverse instruments of our time.
