The harp is one of the oldest musical instruments in the world. The earliest harps were developed from the hunting bow. The wall paintings of ancient Egyptian tombs dating from as early as 3000 B.C. show an instrument that closely resembles the hunter's bow, without the pillar that we find in modern harps.
The angled harp came to Egypt from Asia in about 1500 B.C. It was built from a hollow sound-box joined to a straight string-arm at an angle. The strings, possibly made of hair or plant fibre, were attached to the sound-box at one end and tied to the string-arm at the other. The strings were tuned by rotating the knots that held them.
