The Harp is one of the oldest instruments. It has three important components: the soundbox, the neck and the strings. It has 47 strings made of gut, steel, copper and nylon. They are tuned diatonically in C major. They change the string tune by using seven pedals located at the bottom part of the Harp. If the Harpist moved the C pedal down, all the C notes of the Harp would get flat. The left pedals changes B, C and D strings while the right pedal changes the rest of strings. The Harpist can only change one pedal of each group of pedals while s/he is playing. The C strings are red whereas the F strings are black.
It is played by plucking the string with the fingers, and there are several techniques for doing it. It is pitched in the key of C and as well as the Piano it is notated in two staffs one in treble clef and the another in bass clef. Its playing range starts at the C-flat1 and the highest note you can play is the G-sharp7. Its lower register has a long resonance, whilst the middle register is brilliant and warm. The upper register is very bright, short and penetrating.
