Whitman's poetry has inspired an extraordinary number of musical works - there are some 1200 vocal and instrumental settings of his verse by, among others, Vaughan Williams, Delius, Bernstein, Ives, Weill, Hindemith, Holst and John Adams - and the 'Bard of Democracy's optimistic, inclusive, radically free voice continues to appeal to contemporary composers today.
