The hardest style of piano to play is often considered to be classical music, especially the works of composers like Ludwig van Beethoven, Frédéric Chopin, and Pyotr Ilyich Tchaikovsky. These compositions are characterized by complex melodic lines, intricate harmonies, and rapid transitions. Their difficulty increases further when you take into account the demands they place on finger independence, dexterity, and stamina. In contrast, other styles such as pop and jazz may offer more relaxed tempos and simpler chord progressions, though they still require skill and technique to master.
