Max Reger’s Adaptations of Bach Keyboard Works for the Organ

Thesis (D.M.A.)--University of Washington, 2019The history and performance of transcriptions of works by other composers is vast, largely stemming from the Romantic period and forward, though there are examples of such practices in earlier musical periods. In particular, the music of Johann Sebastian Bach found its way to prominence through composers’ pens during the Romantic era, often in the form of transcriptions for solo piano recitals. One major figure in this regard is the German Romantic composer and organist Max Reger. Around the turn of the twentieth century, Reger produced many adaptations of works by Bach, including organ works for solo piano and four-hand piano, and keyboard works for solo organ, of which there are fifteen primary adaptations for the organ. It is in these adaptations that Reger explored different ways in which to take these solo keyboard works and apply them idiomatically to the organ in varying degrees, ranging from simple transcriptions to heavily orchestrated arrangements. This dissertation will compare each of these adaptations to the original Bach work and analyze the changes made by Reger. It also seeks to fill a void in the literature on this subject, which often favors other areas of Reger’s transcription and arrangement output, primarily those for the piano
