Arnold Whittall (born 1935) is a British musicologist and academic. Whittall's research areas have primarily been centred around the musical analysis of 20th-century music and aspects of the nineteenth-century, such as the music of Richard Wagner. He is Professor Emeritus of Musical Theory and Analysis at King's College London, having worked as Professor there between 1975 and 1996.^[1]

Prior to his King's College London position, Whittall lectured at Cambridge, Nottingham (1964–1969), and Cardiff (1969–1975), and served as visiting professor at Yale University. His students included Australian composer Norma Tyer.^[2]

Since the 1960s, he has contributed extensively to musicology through the publication of books, articles and provided chapters to multi-authored books.^[3] Whittall's initial publications focussed on Benjamin Britten before shifting to 20th-century music more generally. Other publications have addressed key discussions within musicology such as semiotics and modernisms; while others are focussed on the music of specific composers such as Anton Webern, Pierre Boulez, Thomas Adès, and Howard Skempton.
