These regular ‘worldly’ interruptions – some of an almost Bartókian savagery, others gentler and more dance-like – contrast sharply with the predominantly serene, contemplative mood. Another intermittent feature is a rhythmic figure played on a bandir (drum). Tavener’s original idea was for this rhythm to be tapped on the wood of the viola, but he eventually realised that the drum, with its greater resonance and clarity, would be more effective. In Sufi music this bandir rhythm traditionally symbolises the heartbeat. At the very end of the work, following extremely quiet vocalising – ‘Remember me’, supporting the viola melody, then ‘O God’, nothing remains except the drum, now characterising the familiar rhythm with a crescendo-diminuendo. Concerning the work’s performance Tavener advises: ‘Diódia should be played in a church or in a sacred space, with subdued lighting. It is not music for dissection, therefore it should not even be played in a concert hall’. The quartet was commissioned by the West Cork Chamber Music Festival, the City of London Festival, and the Festival de Saint Nazaire, Brittany. Its first performance was given by the Chilingirian Quartet in July 1997, at Bantry House, West Cork.
