Richard Lambert's Silver Threads for Flute duet.
The overall structure of this piece is A B A1 C D A2; melodic and rhythmic motifs are constantly woven (hence the title), overlapped and transformed throughout all sections. Although the whole range of the Flute is used, the rich lower register is especially exploited. Without harmonic support, the work relies on textural variety and busy, rhythmic momentum. Basically tonal, but without an obvious key centre, the work uses mild clashes to provide astringency. A gradually decreasing tempo allows for more reflective playing, before a busier texture increases the pace into a brief return of the agitated initial material, which brings the piece to an energetic conclusion.
