The Harp is one of the oldest instruments dating back to around l200 B.C. The modern double-action or concert harp, with seven pedals, was invented in 1810. This is one of the earliest examples, but very few changes have been made since then. The harp is a regular member of the symphony orchestra and opera orchestra, and is sometimes used to great effect in chamber music.
