Cassation was written in 1960 for players at the Tonbridge Music Centre. ‘Cassation’ is an 18th century term, referring to a suite of several movements, like a Serenade or a Divertimento, which is suitable for outdoor performance. Mary Chandler’s Cassation is scored for wind octet (2 each of oboes, clarinets, horns and bassoons) and has five short movements. It is conventional in shape if not quite in texture and there is an element of pastiche about it, especially in the Valse and the Gigue.
