Harp
Harps vary globally in many ways. In terms of size, many smaller harps can be played on the lap, whereas larger harps are quite heavy and rest on the floor. Different harps may use strings of catgut, nylon, metal, or some combination.

All harps have a neck, resonator, and strings, frame harps or triangular harps have a pillar at their long end to support the strings, while open harps, such as arch harps and bow harps, do not.

Modern harps also vary in techniques used to extend the range and chromaticism of the strings (e.g., adding sharps and flats).

Harp [SEP] Variations
Harps vary globally in many ways. In terms of size, many smaller harps can be played on the lap, whereas larger harps are quite heavy and rest on the floor. Different harps may use strings of catgut, nylon, metal, or some combination. All harps have a neck, resonator, and strings, frame harps or triangular harps have a pillar at their long end to support the strings, while open harps, such as arch harps and bow harps, do not. Modern harps also vary in techniques used to extend the range and chromaticism of the strings (e.g., adding sharps and flats). On lever harps one adjusts a string's note mid-performance by flipping a lever, which shortens the string enough to raise the pitch by a chromatic sharp.
