There is a sharp contrast between the tight and rhythmic central section and the final passage which dispenses with barlines altogether, providing a fascinating journey through interrelated and continuous sections.

This four-movement work represents the composer's desire 'to write a piece of real chamber music, intimate and conversational in tone, drawing the listener into its worlds'. The result, he writes, 'is a rather inward-looking, reflective work, not without a capricious aspect, but only occasionally raising its voice.'.

String quartet - Difficult

SKU: OU.9780193577671

Composed by William Mathias. String Quartets. Score and parts. 108 pages. Duration 29'. Oxford University Press #9780193577671. Published by Oxford University Press (OU.9780193577671).

Mathias' third and final quartet was commissioned by the 1986 Harrogate International Festival and premiered there in August that year by the Medici Quartet. It has three movements: the first takes the form of a sonata, the second starts off as mysterious and lyrical and moves into a fiery climax, and the third uses exciting fugal passages and 'scherzando' sections, which make for a thrilling conclusion.
