Frederick Hohman plays Johann Sebastian Bach's "Fiddle" Fugue in D minor, BWV 539, on the Flentrop organ at Busch Hall (formerly Busch Reisinger Museum) at Harvard University in Cambridge, Massachusetts. This is one instance where J. S. Bach (1685-1750) transcribed a piece for the pipe organ that he originally composed for a different music medium. This fugue is found as the second movement in Bach's Sonata No. 1 for Solo Violin in G minor, BWV 1001. When adapting the fugue for solo organ, Bach transposed the work to the key of D minor, and added many passages which were not in the violin original, which embellish and enhance the work. Therefore, this organ fugue has earned a nickname: "The Fiddle." There are two points in the performance of the fugue where Frederick Hohman alternates manuals, in an echo fashion. Prior to the installation of the Flentrop organ in the late 1950s, Harvard's Busch Reisinger Museum was the home to an organ by Aeolian-Skinner that exhibited the design of its tonal director, G. Donald Harrison. Mr. Biggs was heard playing the Aeolian-Skinner organ over the CBS radio network, with a 15-minute broadcast every Sunday morning, during the early 1950s. The Aeolian-Skinner organ at Busch-Reisinger was removed and replaced by the Flentrop organ seen in this video. It was acquired for Harvard University with the help of concert organist E. Power Biggs. Mr. Biggs made several LP recordings for Columbia Records on this Flentrop organ after 1960.
