Handel’s concertos for organ and Rameau’s concert harpsichord pieces figure among the most original works in the keyboard repertoire of the 18th century. The Dom Bedos organ is one of the rare French instruments from the 18th century equipped with a 32-foot manual organ stop, endowing the grand plein-jeu with an incredible depth. The process of re-working and adapting musical material was a very common practice and some of these harpsichord pieces en concert seem to suit the organ perfectly. Whether it is a reduction of an orchestral work to be played by solo harpsichord, or inversely the development of a work so that it may be played by a larger number of musicians, the 18th century abounds in collections of arrangements of the latest fashionable opera airs. Rameau himself, like Handel, was adept at re-writing and often reused a musical idea under several guises. Play it loud!
