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 nylon-strung classical guitar 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, although many players, particularly fingerpickers, use alternate tunings, such as "open G", "open D", or "drop D". Wikipedia [ - ]
