This volume of eleven essays, compiled as a tribute to Winton Dean on his seventieth birthday, focuses on that area which has absorbed Winton Dean's interest throughout his distinguished career: opera and other theatre music. The first half of the book covers the period from the late seventeenth century to the mid-eighteenth. The second half of the book ranges over later opera: operacomique; Mendelssohn's operas; the influence of Wagner; the finales of Janacek's operas; and Britten's first two major operas, Peter Grimes and The Rape of Lucretia.
