Harp (English: Harp, Italian: Arpa, German: Harfe, Persian: ???), is a large stringed instrument. The harp is one of the oldest plucked string instruments in the world, originating in ancient Persia (Iran).
Early harps only had strings arranged according to the natural scale, and the tonality they could play was limited. The modern harp was designed by French piano maker S. Herard in 1810. It has forty-seven strings of different lengths and seven pedals that can change the pitch of the strings and play all tones.
