Thanks, RdS, for clear and informative answers to my queries. I will be looking out for some performances that utilise this type of mean tone tuning, if only to satisfy my curiosity about the listening experience. I have not heard Verlet's latest set of partitas although her earlier set was quite enjoyable. There is little doubt that she is an excellent harpsichordist, but she is definitely and acquired taste.

In respect of Francois Couperin's works, I have only heard Rousset's interpretations, which are excellent. I was not aware that Scott Ross also recorded Couperin. Incidently, I have Leonhardt's recording of Louis Couperin's Works for Harpsichord which is very well-played. I have heard his Goldbergs, partitas, English Suites, Art of Fugue and Italian Concerto, and they are all of an extremely high standard. He is truly a marvel.

Well actually, pe-zulu, I wanted a good organ recording of the Art of Fugue and Isoir's set seems to have got rave reviews and won many awards. This, in itself, is not indicative of a great recording, but since my knowledge of Bach's works on organ are minimal, I was looking for some guidance in purchasing a worthy copy. I have versions on harpsichord, piano and string quartet, and an organ version would complement them nicely.

Regards.
