Amy Beach was a pathbreaking composer and pianist who transcended the restrictions of nineteenth-century Boston to become America's most famous turn-of-the-century female composer and, later in her career, a prominent performing artist and promoter of music education. The Cambridge Companion to Amy Beach makes her life and music accessible to a new generation of listeners. It outlines her remarkable talent as a child prodigy, her marriage to a prominent physician twice her age, and her subsequent international acclaim as a composer and piano virtuoso. Analytical chapters examine the range of her musical output, from popular songs and piano pieces to chamber and symphonic works of great complexity. As well as introducing Beach's compelling music to those not yet familiar with her work, it provides new resources for scholars and students with in-depth information drawn from recently uncovered archival sources.
