Piano repertoire refers to the collection of musical pieces that a pianist can perform or study. This repertoire can include a wide range of styles, from classical compositions by composers like Ludwig van Beethoven and Frédéric Chopin to contemporary works. Pianists often select pieces that showcase their skills and express their musical interests. The repertoire is typically categorized by difficulty levels, allowing pianists of all ages and skill levels to find suitable pieces. Many music schools and conservatories encourage students to build their repertoire through practice and performance, helping them develop their technique and musicality over time.
