Like Robert Schumann who often favoured the horn, Sir Michael Tippett who died on 8 January 1998 makes full use of the instrument&lsquo,s tonal possibilities in this work. He translated the Romantic genre of horn quartet into a modern tonal language: ''All movements contain characteristic calls and triad arpeggios. Sometimes the call itself is the theme, as in the fugue. Sometimes the calls are the accompaniment to a solo, such as in the nocturne.'' (Tippett) The forms of the four movements, however, are traditional. The structure of the fist movement is reminiscent of the form of a strophic song. The second movement is an allegro, the slow third a nocturne in the traditional ABA form. And fially the last movement is a capricious fugue.
