A HARP is a four-letter many-stringed instrument that has been used for centuries in various cultures. It is a stringed instrument that is played by plucking or strumming the strings with the fingers or a plectrum. The strings are attached to a soundboard, which amplifies the sound. Harps come in many shapes and sizes, from small lap harps to large concert harps. They are often used in classical, folk, and religious music.
