In creating the music that would reflect the work’s principal themes, my first concern was to define a harmonic language that might inflect and energise Euripides’ stratification of Greek society (gods, citizens, slaves) and determine how different characters embodied harmonic material. I also wanted to find a poignant and enduring symbol for the tender love that beats at the heart of the story, the love that joins Ion to Creusa, a son to his mother, and through her to Apollo. It had to be a symbol rooted in acoustic phenomena, aurally recognisable and not a mere abstraction.
I chose the simplest of means, by placing the interval of the perfect fifth at the centre: this first overtone after the octave would be the engine that would drive the harmony. Since much of the action of the drama seeks to connect Ion to his divine origins (he is Apollo’s son) and since the action of Apollo has such far-reaching consequences for the humans embroiled in the drama, the interval of the fifth permeates the music of all the principal characters. It is the principle leitmotiv amongst many. Chords based on stacked perfect fifths, the interval cycle of the 5th taken as a whole (the only cycle capable of going through 12 positions without repeating a pitch), other harmonies based on the fifth, whether in bursts of chords or melodic lines, symmetrical modes that affirm or deny the circle of fifths, these were the various means by which a multi-layered palette was created that could separate the worlds of gods, citizens and slaves, and yet find common threads running through them.
When I begin work on an opera, I often start with rough graphic drawings, an attempt to map each scene’s contours, texture and rhythmic quality in free-hand lines and colours. My impression of colour when I first read Ion was heightened when I encountered the sculptures of Anish Kapoor in 1998 as I began work. The raw energy-drawings eventually led to hundreds of rhythmic templates where the vocal line was paced against orchestral space in order to create a unified rhythmic-textural design. This allowed me to control the flow of text precisely and define the strands of counterpoint. There was also the problem of holding together long stretches of recitative in some unifying classical structure that would free the music from illustration. My solution was to impose taaltaals that could underpin long recitatives and help characterise the declamation. cycles based on the conjunction of small rhythmic cells,
As regards orchestration, one strategy was to associate the principal characters with characteristic instrumental timbre; for example, Ion is often accompanied by solo cello, Creusa by solo viola and the Pythia by contrabass clarinet. Since string instruments are used to light up characters with the greatest degree of individuation, I avoided strings for the five Servants of Creusa; their accompaniment is primarily the ensemble of five woodwind instruments as in the opening scene, with successive choruses cumulatively enhanced by the addition of piano, percussion and brass.
When Ion was first presented in Aldeburgh and London in 2000, conductor David Parry and director Steven Pimlott devised a compelling presentation using a narrator to fill in sections that were not ready, in order to produce a complete theatrical experience. However I saw it as work in progress and there was never any question in my mind that the opera needed to find completion as originally designed. So the gaps were indeed plugged, but I also went back over other material and revised extensively.
As for the future, opera will, I hope, continue to be an important focus in my output. It has always seemed to me the perfect vehicle for the expression of social and political ideas, and the exploration of human consciousness across a wide panorama. I am planning to write another full length opera in collaboration with dramatist David Rudkin. Beyond that other projects linger on the horizon. However, for now it is the newly-completed Ion that holds centre-stage and it has been a privilege to work with the fine production team of Music Theatre Wales, led by conductor Michael Rafferty and director Michael McCarthy, to shape these first performances that help Ion find its way in the world.
Ion is dedicated to my friend Bill Casey for so many years of inspiration and friendship.
