This book concerns the life and theatrical career of the great native-born English composer and musician of the eighteenth century, Thomas Augustine Arne (1710-1778). Its purpose is three-fold. First, it provides a comprehensive biography and account of the performance and publication of Arne's works during his lifetime. Although Arne's childhood years get some attention, the book focuses on the period from 1732 to 1778, a time of great innovation for English opera and related genres. Second, it considers Arne's social context: his relationships with the many dramatists, actors, singers, and fellow composers and instrumentalists--including many members of his own family--with whom he collaborated on the London and Dublin stages as well as at the London pleasure gardens. Third, it offers analysis of eighty musical illustrations drawn from vocal works for the theatre spanning Arne's career, and readers can simultaneously study and listen to the musical examples on a companion web page that hosts media files produced using music notation software. The audio component constitutes a crucial supplement to a study of Arne because so much of his extant theatre music cannot otherwise readily be heard. Arne was the leading figure in English theatrical music of his day. Dr. Charles Burney, the great eighteenth-century historian of music, had a high opinion of the composer, especially of Arne's setting of Milton's Comus (1738): "In this masque he introduced a light, airy, original, and pleasing melody, wholly different from that of Purcell or Handel, whom all English composers had hitherto either pillaged or imitated. Indeed, the melody of Arne at this time . . . forms an era in English Music; it was so easy, natural and agreeable to the whole kingdom, that it became] the standard of all perfection at our theatres and public gardens." Yet Burney's greatest compliment concerns Arne as a composer of secular vocal music: "He must be allowed to have surpassed Purcell] in ease, grace, and variety." During his forty-six-year career Arne composed music for over 100 stage works--to say nothing of his myriad single songs, cantatas, and instrumental compositions. Yet despite a relative wealth of source material, scholars of theatre, drama, and music in our own time have almost completely ignored him. As a consequence, musicologists, theatre historians, and laypeople alike tend to evince a detrimentally limited sense of the magnitude of Arne's contribution to English music and especially to the history of English opera.
