sofe i have no idea, it could be to do with the number of strings? It was one female and one male harpist playing together and it was interesting how his instrument was more baritone- Either by design or just the notes he was playing. They had translated traditional greek songs to harp and had two singer join them as well. Quite the experience for ten euro!!
Harpsichord: a musical instrument similar to a piano. It was played especially in the 17th and 18th centuries. Learned from: the short story The Garden of Time by J.G Ballard. You can read the story here.
