The harp is a unique stringed instrument and can be classified as a member of two families—the string family and the percussion family. As a member of the string family, the harp contributes a beautiful, melodic sound, but instead of having four strings like the violin, viola, cello and bass, it can have up to forty-seven! As part of the percussion family, the harp often plays a supportive, rhythmic role. To play the harp, you sit down with the instrument leaning on your shoulder and pluck the strings with your fingertips. You can change the pitches of each string by using the seven foot pedals at the bottom of the harp.
