A music auction on 28 May at Sotheby's, London, will offer several interesting items.

Some big lots are the autograph manuscript of Rachmaninov’s Symphonic Dances for 2 pianos, Tchaikovsky’s working draft of his Suite no.2, Stravinsky’s Berceuses du chat, two music manuscripts by Mozart, as well as manuscripts by Offenbach, Strauss, Balakirev, Scriabin, Boulez, Wagner, Debussy and Delius. There are also letters by Beethoven, Mendelssohn, Chopin, Tchaikovsky and Wagner, and a very early score of Handel’s Acis and Galatea.

The printed items include a copy of Sanquirico’s designs for La Scala, the huge Graduale Romanum printed by Giunta in 1499, and first editions of Purcell and Mozart. There are also paintings by C.G. Jung and Mendelssohn and an important early miniature portrait of Kant.

As curiosities two locks of of hair will be on offer: one from Mozart and one from Beethoven.
