The acoustic guitar is one of the most common guitars used by musicians which use purely acoustic methods to produce the sound, hence the name acoustic guitar.
How An Acoustic Guitar Creates Sound
The acoustic guitars have a hollow body and a sound board on the face of the guitar. The sound board has a small hole at its center and is often referred to as a sound hole. The sound box in the acoustic guitar improves the way the instrument resonates, thus improving the quality and volume of the sound.
Acoustic guitars are made up of six strings which when struck vibrate, thus causing the soundboard to vibrate. Due to the larger surface area of the soundboard, they displace a large amount of air producing a larger sound than that produced by strings alone. The pickups installed in the soundboard of the acoustic guitar further help in amplifying the sound. The pickups used in acoustic guitars are magnetic and piezoelectric pickups. Magnetic pickups are installed inside the sound hole while piezo pickups are installed under the bridge saddle of the acoustic guitar.
What Are They Made Of?
Acoustic guitars are made up of various materials. The materials used in the construction of acoustic guitars make a great impact on the sound produced. The type of guitar will also sometimes call for specific materials. Also different materials are being used for the various parts of the guitar including the top, sides, back and neck.
The material used for the top of the acoustic guitar is extremely important in determining the sound quality. The top of the guitar i.e. the soundboard is made up of either pine, koa, Sitka spruce or cedar. The most commonly used wood for the tops of many good quality and expensive acoustic guitars is Sitka spruce. Rosewood, maple and mahogany are commonly used for the back and the sides. Darker woods are commonly used for the sides and the back. Maple, ebony, rosewood and mahogany are the woods commonly used for the construction of neck in acoustic guitars.
The Shape
The size and shape of the acoustic guitars also play a major role in the tone produced. Two guitars which are made of same materials but different shapes or sizes produce sound, which slightly differ from one another. Most acoustic guitars have waist shaped or narrowing body which helps in resting guitars on the knees.
There are different varieties of acoustic guitars, two of which are classical guitars and steel stringed acoustic guitars. Classical guitars are nylon stringed instruments which allow performing even the complex of the polyphonic and melodious tunes. Steel stringed guitars are similar to the classical guitars but have steel strings instead of nylon strings and hence have a louder and brighter sound. Acoustic guitars were basically intended for classical and folk music, but are used in all styles of music.
