Steel-string acoustic guitar
The steel-string acoustic guitar is a modern form of guitar that descends from the gut-strung Romantic guitar, but is strung with steel strings for a brighter, louder sound. Like the modern classical guitar, it is often referred to simply as an acoustic guitar.

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), drop D (D-A-D-G-B-E), or D-A-D-G-A-D (particularly in Irish traditional music).
