Concert Grand Harp
47 strings, 7 pedals, and pure ethereal sound/Musical Instruments
A concert grand pedal harp stands about 1.85 meters tall, has 47 strings spanning 6.5 octaves, and weighs around 36 kg. Its 7 pedals each have three positions that mechanically alter string length, allowing the harpist to play in any key. The total string tension is about 730 kg, which is why the column and frame must be incredibly strong.
