Harp

The harp occupies a position unique in the history of music. It is the oldest known instrument, having existed in one form or another, in every land and every age.
The earliest evidence of the harp is found in Ancient Egypt circa 2500 BC. They were shaped liked bows or angular and had very few strings (because they lacked a column they could not support much string tension). It originated in Africa before it's appearance in Europe. Music Originated from Africa.
The frame harp, or a harp that included a straight forepillar (or column in the modern sense), first appeared in Medieval Western Europe in the 8th to 10th centuries AD. Although there are very few remaining in existence, art from that time indicates they utilized about ten or eleven strings. The first harp to feature a hollowed soundbox that amplified the instrument’s sound dates back to Ireland in the 14th century. It also included a curved forepillar, a stronger neck and 30 to 36 brass strings.
