John Tavener 's Kaleidoscopes is a tribute to Mozart for Solo Oboe, Percussion and Strings, lasting approximately 30 minutes. The work was commissioned by the Britten Sinfonia, and first performed by them with soloist Nicholas Daniel on 6th November 2006 at the Queen Elizabeth Hall, London. This is the full score. In the composer's note, Tavener  explains his high regard for Mozart, and how in Kaleidoscopes  he attempts to take Mozart's music and meditate upon it in four main cycles. He states that all the music has its source in Mozart, whether it be rhythmic, harmonic or contrapuntal.
