As a harpsichordist and organist, Dr. Farr specializes in the performance and stylistic practices of keyboard music of the 16th-18th centuries, as a recording artist, solo performer, and ensemble director and player. She also performs on the pedal-harpsichord. Performance and the vivid communication of musical ideas are her primary interests. In support of these goals, she has been particularly interested in the harpsichord repertoire of the English Virginalists and the French clavecinists, North German organ repertoire of the 17th century, and the music of J.S. Bach, and areas of basso-continuo practices, tuning (temperaments), characteristics of the keys, rhetoric and form, and musica ficta in keyboard music of the 16th and early 17th centuries. She also performs organ repertoire of the 19th-20th centuries, and is interested in the various styles of harpsichord and organ building and design during the last four centuries and the influence of these on the repertoire itself.
