Acoustic slide guitar tuning involves adjusting the strings of an acoustic guitar to create a distinctive, resonant sound. Typically, the strings are tuned to an open tuning, such as open D or open G, which allows for easy slide guitar playing and creates a rich, full sound.
This tuning is particularly suitable for slide guitar playing, as it allows the player to slide the metal or glass slide along the strings, creating a smooth, ethereal sound. It is often used in blues, folk, and rock music, and has been popularized by musicians such as Ry Cooder, Duane Allman, and Derek Trucks.
