Book excerpt: The New Grove Dictionary of Music and Musicians is the most up-to-date body of musical knowledge ever gathered together. The New Grove composer biographies have been selected from the dictionary to bring the finest of the biographies to a wider audience. Each has been expanded and updated for book publication and contains a comprehensive work-list, index, and fully revised bibliography, in addition to the definitive view of the subject's life and works. The great traditions of Russian music began in the mid-19th century with Mikhail Glinka—the father figure for the next generations of Russian composers. His direct heirs were 'The Five,' or 'The Mighty Handful,' drawn together by Mily Balakirev, the teacher of two leading figures in the group: Alexander Borodin, creator of Prince Igor and quartets of an unmistakably Russian flavor, and Modest Musorgsky, creator of the greatest Russian epics of the lyric stage. Slightly apart from this group because of his more cosmopolitan approach to his art stands the most-loved of all Russian composers, the ever-appealing Tchaikovsky.
