A lever harp is a type of harp that features a series of levers attached to its strings. These levers allow the player to easily change the pitch of the strings, enabling them to play in different keys without needing to retune the instrument. Lever harps are typically smaller and more portable than traditional concert harps, making them popular among folk musicians and for casual performances. The design of the lever harp dates back to the 19th century and is often associated with Celtic music. Many players appreciate its versatility and the ability to produce a wide range of sounds. Lever harps are commonly used in various genres, including classical, folk, and contemporary music.
