Percy Aldridge Grainger (1882-1961) was an Australian-born composer, pianist, and music educator known for his contributions to classical music and the early 20th-century folk music revival. He primarily worked in the genres of classical and folk-inspired music, blending traditional melodies with innovative orchestration. Notable works include "Lincolnshire Posy," a suite for band based on English folk songs, and "Country Gardens," a piece for piano that became widely popular. Grainger was also a pioneer in the use of electronic music and experimental techniques, which he explored through his compositions and performances. Grainger's impact on music extends beyond his compositions; he was a strong advocate for the preservation of folk music and collected numerous folk songs during his travels, influencing later generations of composers and musicians. His unique approach to rhythm and melody, as well as his emphasis on the emotional expressiveness of music, helped shape American and Australian musical identity in the 20th century. Additionally, he was a prominent figure in promoting the use of wind bands, contributing to their development and repertoire.
