Contains 5,000 entries on composers, most of which include up-to-date worklists, along with entries on conductors, performers, directors, critics, producers and designers of international repute, writers and scholars. Entries also cover individual works, including operas and ballets, orchestras and companies from around the world, famous opera houses, concert-halls, and musical festivals. Musical terms and styles, as well as forms ranging from operatic, vocal, and film scores, to song cycles, chamber, hymns, barbershop, and oratorios are covered, as are general themes such as musicology, acoustics, and absolute pitch, and historical periods such as the Byzantine era. Entries also include a wide range of musical instruments, from the familiar—strings, wind, and brass — to the less familiar — aeolian harp, bamboula and sackbut.
