Claude Debussy (1862-1918) was a great harmonic innovator and one of the most original musical voices of the twentieth century. He created fresh, new tonal perspectives without abandoning tonality itself. With a revolutionary sense of instrumental colour and a fleeting, atmospheric sound world, he is often described, rightly or wrongly, as an 'Impressionist' composer. This book presents a clear narrative history of Debussy's life, work and cultural context along with essential reference material and striking illustrations, making it a vital purchase for anyone interested in the composer.
