Almost all categories of instruments were represented in Mesopotamia and Egypt, from clappers and scrapers to rattles, sistra, flutes, clarinets, oboes, trumpets, harps, lyres, lutes, etc. As early as 2600 B.C. harps and lyres are attested at Ur. In the New Kingdom, Egypt borrowed several instruments from Mesopotamia: the angular vertical harp, square drum, etc. The organ, invented in Ptolemaic Egypt, is first attested in its new, non-hydraulic form in the third century A.D.
