This landmark edition, by Barry Cooper, satisfies the exacting requirements of performer, teacher, and scholar. It is totally faithful to Beethoven's music text, corrects long-standing errors and misconceptions, and includes the latest research from Cooper, a world authority on Beethoven. Unlike other editions, the complete 35 sonatas are included, beginning with WoO47 Nos.1-3. For the performer or teacher, there are realized ornaments, suggested fingerings, sympathetic page turns and layout -- all beautifully presented -- and an Introduction on performance practice, articulation, dynamics, pedalling, etc. Every sonata comes with a critical Commentary, including the work's history, a full assessment of the sources, and detailed notes on interpretation. Available as three separate volumes, and as a boxed set. Comes with bonus audio CD of commentary and demonstrations.
