Composer's note:''Quartet' when mentioned in the context of concert music is generally assumed to mean 'string quartet'. In my case the quartet hat has played a central role in many of my pieces (besides the string quartet) is that of two pianos and two percussion. It appears like that or in expanded form with more pianos or more percussion in The Desert Music Sextet Three Movements The Four Sections The Cave Dance Patterns Three Tales You Are (Variations) Variations for Vibes Pianos and Strings Daniel Variations Double Sextet and Radio Rewrite . In Quartet there is just this group alone: two vibes and two pianos. The piece is one of the morecomplex I have composed. It frequently changes key and often breaks off continuity to pause or take up new material. Though the parts are not unduly difficult it calls for a high level of ensemble virtuosity. The form is one familiar throughout history: fast slow fast played without pause. The slow movement introduces harmonies not usually found in my music.'
