Instances where composers have hidden something in their works… sometimes for the sheer ingeniousness of being able to do it… sometimes to send a secret message to someone… sometime to create a puzzle for generations to come… sometimes to create a tortured ambiguity of meaning. The music is from a pretty eclectic mix… Johann Sebastain Bach, Wolfgang Amadeus Mozart, Robert Schumann, Johannes Brahms, Alban Berg, Dmitri Shostakovich and Edward Elgar. Lots of Secrets.
