The title is drawn from a long poem by George Chapman (1559-1634), which is one of the fullest explorations of this theme, where melancholy is no longer an inert and depressive mood, but a humour of the night, an inspired spiritual condition.
I took inspiration from two dark sources – the expressions of melancholy in Albrecht Dürer's engraving Melencolia I (1514) and John Dowland's lute song In Darkness Let Me Dwell, the first three notes of which are quoted in the piccolo's solo soon after the opening of the piece. This motif, which rises a semitone and down again, is woven into the fabric of the work and also alluded to figuratively: lines split and later reunite, the notes of a chord move away and back again, and longer melodic lines are interrupted and resumed like the moon shining through a series of slowly passing clouds.
