Laszlo Somfai, former head of the Bartok Archives in Budapest and professor emeritus of musicology at the Franz Liszt Academy of Music, is a leading authority on Haydn's keyboard music. Charlotte Greenspan, now an independent scholar, has taught music at the University of Wisconsin - Madison and Cornell University.
""Somfai's book has been in print in Hungarian for some years now, and it is no exaggeration to say that it has changed dramatically the manner in which not only Haydn, but to a great extent Mozart and Beethoven as well, are played in that country. My own interpretations have benefited enormously from Somfai's work, and every serious student of this repertoire should consider this study essential."" - Malcolm Bilson, Cornell University""
