This new edition is more scholarly but less comprehensive in scope than its predecessor. Undeniably there are some improvements. For example, many topics are covered in greater depth and detail than in previous editions. It is encouraging to see more detailed biographies of Spohr and Vanhal, to name just two composers who received unduly brief coverage at the hands of Scholes. However, there are also some significant lacunae, such as the extraordinary and indefensible omission of any reference to George Onslow (1784-1853), whose chamber music is currently undergoing a long-overdue revival (no thanks to this book). Although there are some diagrams and musical illustrations, this edition is otherwise without pictures, which makes for a far duller and less 'browseable' book than its illustrious predecessor. All in all, a rather disappointing successor to Scholes.
