[3] Born in Detroit, Michigan, Rosenberger studied in the U.S. with Webster Aitken and Katja Andy; in Paris with the legendary Nadia Boulanger; and in Vienna with the harpsichordist and Baroque scholar Eta Harich-Schneider and the Schenker theorist Franz Eibner.

Rosenberger spent those ten years of seclusion and rehabilitation partly in Vienna, studying Baroque style and theory at the Academy and absorbing German lieder, opera, instrumental music and literature.

At USC she taught a workshop for instrumentalists and vocalists entitled "Preparation for Performance", which drew upon the techniques she had developed to rehabilitate her own playing from the after-effects of paralytic polio.

Her recording of Howard Hanson's Fantasy Variations on a Theme of Youth, with Gerard Schwarz and the New York Chamber Symphony[6] brought her a 1991 Grammy nomination for Best Performance, Soloist with Orchestra.

Night Moods[11] was the successful sequel, and a second water-music disc, Singing on the Water,[12] included barcarolles written especially for the album by Sir Richard Rodney Bennett and David Diamond.

Together with label founder and co-producer Amelia Haygood, Rosenberger led the way into another area of concept recordings with the 1989 release of her Perchance to Dream: A Lullaby Album for Children and Adults,[13] which was one of the first classical CDs designed primarily for young people.
