The most remarkable composer of song literature in the history of Western music, Franz Schubert sometimes gets overlooked in favor of his more bombastic contemporaries. 1997 marks the bicentennial of his birth; record companies and concert programmers, who love such pegs, have accordingly scheduled loads of Schubert for the year. You can find some useful insights into the composer and his work with this biography, a slightly expanded version of the essay written for the New Grove Dictionary of Music and Musicians. Also helpful is the detailed chronicle of his music, arranged by type and date of composition.
