The piano was invented in 1709 by Bartolomeo di Francesco Cristofori in Italy. It was an improvement over previous stringed instruments like the harpsichord as it allowed for dynamics (loudness and softness) when playing. The piano was then further advanced through technological innovations like the player piano, digital pianos, and continues to be improved upon today while traditional acoustic pianos are also still made with new materials. The piano became a popular instrument for composers to write for due to its expanded capabilities over predecessors.
