Commissioned by the Scottish Ensemble with support from the Friends of the Scottish Ensemble. This version for orchestral strings was arranged by Martyn Brabbins for BBC Total Immersion. First performed by the BBC Symphony Orchestra conducted by Martyn Brabbins at the Barbican concert hall, London, on 15 February 2014.
One "force" an "arioso" is based around the harmonic field of E and is melodic, tonal, straightforward, and, at times, emotional. It is mainly led by the first violin. The other "force" led by the double bass, is strongly discordant [at first a single note F later gradually growing to a giant cluster]. It is essentially chordal [non-melodic], static, suffocating, inexorable and impersonal. Its only contrast is getting louder or getting softer, getting denser, or less dense.
The interruption of the opening "arioso" by a single note F on the double bass is at first not very threatening and the reaction to it is one of surprise. Later as the threat increases so the reaction becomes stronger; at first one of irritation, then anger. A passionate outburst on the violins follows which falls on deaf ears. Then a solo violin, solo viola and solo cello all appeal in turn: still no response. Finally only fragments of the original "arioso" are heard before dying away.
Whereas near the beginning of the work the F on the double bass was an intrusive discord to the E of the "arioso", now at the end a high lingering E on the solo violin [all that is left of the original "arioso"] is a discord to the giant cluster based on F.
Many parallels to this conflict can of course be drawn from real life. The title "Green" for me represents either the freshness of youth, or for the plant life in our world on which we all depend.
