My first debt of gratitude is to the late M. D. Calvocoressi, who
helped me with advice and information when I first planned this
book. Richard Capell read the manuscript and gave me much
valuable advice on many matters, from presentation to typography.
Edward Sackville-West helped me substantially in compiling the
'Other Arts' column of the end-tables. Felix Aprahamian was
generous in putting scores at my disposal. M. and Mme. Tony
Mayer helped me to obtain the illustrations I wanted from France.
Finally the library staff of the Paris Conservatoire and the British
Museum were always helpful, often under considerable provoca-
tion.
