Flemish composers were musicians from the Flanders region, which is part of modern-day Belgium. They played a significant role in the development of Renaissance music during the 15th and 16th centuries. Notable figures include Josquin des Prez and Orlando di Lasso, who contributed to the rich tradition of choral and polyphonic music. These composers were known for their intricate vocal harmonies and innovative use of counterpoint. Their works often featured sacred themes, reflecting the influence of the Catholic Church. The legacy of Flemish composers continues to be celebrated in classical music today.
