For Sydney is a Lullaby and Dance named for the composer's young daughter, and one can hear the household calm followed by the burst of spirited exuberance in these paired movements. Part of Harberg's special palette is the simultaneous strength of musical structure along with boisterous fun. For Sydney is a tour de force in blending these traits, while remaining idiomatic for the violist. For advanced violists.

Harberg's Prayer is a rarity in the modern concert repertoire, beautiful romanticism built of a haunting aria for solo viola. Within the reach of younger players, Prayer has been championed by top professionals for its expressive and dramatic power and aura. The acclaim for this work has led to versions for orchestra, for a variety of other solo instruments with piano, and to the slow movement of Harberg's Concerto for Viola and Orchestra.
