An acoustic guitar is a special musical instrument, probably the most unique one in the entire guitar family. Its strings vibrate a hollow metal body on a resonating metal resonator to produce a sound vibration through the air. Acoustic guitars are usually tuned by plucking the strings with a flat pick or with the help of a pick cap. It can be categorized as a classical guitar, jazz guitar, rock guitar and folk guitar. Since it is quite easy to strum, most acoustic guitars are made with steel strings.
The cost of an acoustic guitar might vary depending on its brand, the material of its body and the number of frets. You can buy a complete guitar with all the needed hardware and tune it yourself at home. However, if you want your guitar to have more powerful tone, you can buy a high end model that would require professional tuning. It will also have additional features like electronics and other amplification systems. Read more about breedlove parlor guitar.
Although an acoustic guitar has a distinguished sound of its own, it is not that easy to imitate. Classical guitarists are able to create melodic sounds by changing the string gauge, using bent notes, vibrato, slides and other techniques. Acoustic guitarists rely mostly on their fingernails for intricate changes in tone. For improvisation and rapping, a bit more dexterity is needed. Finger style is also important for some acoustic guitarists.
Tuning is usually done by plucking the strings with the index finger and the thumb, or sometimes both. Some acoustic guitarists prefer to depress their fingers completely down to the fifths of an inch, while others find it easier to depress half-tones to an inch. Electric guitars usually have open tunings, but acoustic guitars have closed tunings.
The shape of the neck of an acoustic guitar has significant effects on the tone. When the neck is bent, as in playing a classical guitar, the strings tend to move farther apart. If you play an acoustic with a flat neck, the distance is less and the tone is better. On the other hand, the curve in the neck of the acoustic makes it easier for the strings to slide along the neck, which produces a deeper tone. Read more on 12 string acoustic guitar.
Lastly, the material of the acoustic guitar strings is also important. Acoustic guitar strings made of nylon, plastic or steel are easier to finger, making it easier to produce a deeper tone. On the other hand, nylon strings tend to have a looser feel, which results in a lighter touch. Steel strings are the best choice for acoustic guitar players who perform along with their electric guitar.
