Editing Robert Simpson (composer) (section)

===Other chamber music===
; Clarinet Quintet (1968)
: This is a large-scale work in five movements forming an arch shape&nbsp;– a central scherzo of some 800 bars is framed by two slow movements, which themselves are framed by two outer fast movements. The arch shape is completed by a slow introduction and a slow coda. The entire basis of the material for the work is outlined in the opening introduction, with the main theme having some sort of parallel with Beethoven's C sharp minor quartet. It is one of Simpson's more subtle and enigmatic scores, with an epilogue of almost naive, diatonic fluidity and rising scales.
; Violin Sonata (1984)
: This is a two movement structure, the first movement a vigorous Allegro, and the second combining the characters of a slow movement, scherzo and finale. Throughout there is a conflict between G major and G minor&nbsp;– particularly guided by the intervals of a major third and a minor third, which are often combined and pushed against each other to create strange resonances&nbsp;– for example G to B flat in the low register of the piano, and B natural to D in the upper register.
; String Trio (1987)
: A three movement work. An opening Prelude (Presto) and a concluding Fugue (Volante) are separated by a central Adagio. It is dedicated to Jillian White of BBC Bristol.
; String Quintet No. 1 (1987)
: A long one-movement work alternating slow and fast sections. It contains some of the most peaceful music the composer ever wrote.
; String Quintet No. 2 (1995)
: This was Simpson's final work. Most of it was completed in 1991, before Simpson was paralysed with a stroke that left him in permanent pain, but the final coda was dictated to his wife several years later. It is one of Simpson's most severe and dark scores, its structure is built on a minimal amount of material and there is an alternation between two tempo types&nbsp;– an austere, lyrical moderato and a knotty allegro. The slow, final coda is one of the darkest endings in all string chamber music literature.
