The steel-string acoustic guitar is a modern form of guitar that descends from the classical guitar, but is strung with steel strings for a brighter, louder sound. It is often referred to simply as an acoustic guitar, though the classical guitar with nylon strings is also sometimes called an acoustic guitar. The most common type is often called a flat-top guitar, to distinguish it from the more specialized archtop guitar and other variations. The standard tuning for an acoustic guitar is E-A-D-G-B-E (low to high), although many players, particularly fingerpickers, use alternate tunings (scordatura), such as “open G” (D-G-D-G-B-D), “open D” (D-A-D-F-A-D), or “drop D” (D-A-D-G-B-E).
An acoustic guitar is a guitar that uses only acoustic means to transmit the strings’ vibrational energy to the air in order to make a sound. Acoustic means not electric or using electric impulses (see Electric guitar). The sound waves of an acoustic guitar are directed through the body of the guitar creating a sound. This typically involves the use of a sound board and a sound box to strengthen the vibrations of the strings. The main source of sound in an acoustic guitar is the string, which is plucked with the finger or with a plectrum. The string vibrates at a necessary frequency and also create many harmonics at various different frequencies. The frequencies produced can depend on string length, mass, and tension. The string causes the soundboard and sound box to vibrate, and as these have their own resonances at certain frequencies, they amplify some string harmonics more strongly than others, hence affecting the timbre produced by the instrument.
