Among his many compositions, Kenneth V. Jones wrote a concerto for string orchestra (1956), a concerto for oboe and strings (1963), The Pollock, an orchestral prelude (1963), O Light Invisible, a cantata for soprano, mixed chorus and orchestra (1963), a sonata for solo violin (1967), Dialysis, for violin and harpsichord (1973), Quaquaverse, for saxophone quartet (1979), Paean for organ (1983), three Sinfonias for orchestra, as well as piano works, song cycles, film, play and television scores and church music, including hymns and anthems. Quinquifid for Brass Quintet (1980) was written for Equale Brass, who premiered the piece in the Purcell Room on 6 December 1980. Quinquifid was first broadcast by the BBC on Radio 3 on 30 December 1981. The structure of this work is built on a notion of five sections, each linked without a break by cadenzas for each of the solo instruments. The opening movement begins with an Andante introduction flecked by flutter-tongued trumpet and moves into a more urgent Allegro section that exploits the lyrical qualities of the tuba to expressive effect. Gradually the music intensifies, building to a powerful climax, before falling away abruptly, paving the way for the next section, a brief duet for the two trumpets, marked 'Shadow Play' in the score. Light and lively, the finale offers flowing interplay between the instruments and brings the score to a confident conclusion.
