An acoustic guitar is a special musical instrument in the acoustic guitar family. It is made with a hollow body and is similar to the classical guitar, except that it does not have a steel neck. Its strings vibrate a tuned sound board onto a resonating metal body in order to generate a sound wave as it passes through the air. Since this instrument uses hollow bodies to generate its sound, it is often called an acoustic guitar.
When learning to play the acoustic guitar, a player can choose from nylon strings or steel strings. The nylon strings produce a more mellow tone and are usually recommended for beginners. On the other hand, steel strings are used when a player wants a harder tone. Some acoustic guitars contain a “choke” tone, which sounds very dramatic when the nylon strings are used because it adds extra emphasis to the notes.
Acoustic guitars use two different kinds of amplification. One works on the principle of direct action and the other is far more complex, known as feedback. The feedback tone of the acoustic guitar occurs when the strings are struck and rebound, creating an electric field that causes some of the sound energy to be transferred to the amplified sound. This is one reason why feedback is usually a component of the electric guitar signal chain. The electric guitar, however, has a valve that can control the amount of feedback, so that the effect is negligible.
Another distinctive feature of acoustic guitars is their dreadnought shape. Dreadnought means the instrument has a neck that extends far beyond the rest of the body. The extended neck permits the guitarist to reach the high notes with only the sixth and fifth fingers. Many classical musicians considered this shape the most convenient for producing deep and powerful bass lines. Some contemporary guitarists also favor the dreadnought style. Many contemporary acoustic guitars have a double cutaway body, permitting the sixth finger to be comfortably positioned over the twelve and a half inch “thumb” part of the fret board.
The traditional position of the soundboard on an acoustic guitar is also different from those used in electric guitars. In an acoustic guitar, the soundboard is located above the sound hole. In an electric guitar, it is typically located below the sound hole. This positioning gives acoustic guitar’s the advantage of using both hands for the same musical task, which is amplified by the amplified sound of the strings.

The third difference is the bridge. In an acoustic guitar, the bridge permits the guitarist to change the tension of the strings without affecting the string gauge. Strings with the same gauge can be strung at the same distance from the bridge, resulting in a very consistent tone. Strings that are too far away from the bridge will not have enough room to stretch, resulting in a muddy, sloppy sound.
