Harp The harp is an instrument of great antiquity, represented from as early as 3000 B.C. in Sumeria. The form of the instrument has varied, but the modern double-action harp, a development of the early 19th century, is in general orchestral use. The strings are tuned in flats,starting from a bottom C flat, with seven pedals, each of which can change a given set of strings to a natural or a sharp. The C pedal, therefore, in its three positions, can make all the Cs on the instrument flat, natural or sharp. Other forms of harp survive. The Aeolian harp, with strings of the same length and pitch but of different thicknesses, was to be placed by an open window, its sounds produced by the wind blowing through the strings. Various forms of Celtic harp are still in use. |
