Programmatic considerations in Julius Reubke's Organ Sonata on Psalm 94
The Organ Sonata on Psalm 94 of Julius Reubke (1834–1858) is perhaps the best example of programmatic music in the organ repertoire—wholly unusual for a mid-nineteenth-century composition in multiple regards. Firstly, composers and performers exploited the expressive and virtuosic capabilities afforded by the piano. The use of the piano in solo and collaborative works was undoubtedly a hallmark of nineteenth-century composition. In contrast, relatively few major compositions for the organ were produced during this period.
