A steel guitar is a type of stringed instrument that is played by sliding a metal bar or "steel" along the strings, producing a smooth, gliding sound. It is commonly used in genres like country music, Hawaiian music, and blues. The instrument can be played in various forms, including the lap steel guitar and the pedal steel guitar, each offering unique features and playing techniques. The lap steel guitar is typically played while resting on the player's lap, while the pedal steel guitar includes foot pedals that allow for pitch bending and complex chord changes. Both types have a distinctive sound that adds depth and emotion to musical performances, making them popular among musicians and audiences alike.
