This tour de force for viola and piano consists of two movements that are complete opposites of each other. The first movement, entitled Momentum, starts with the viola and piano aggressively sharing a single note. Things start swirling out of control: the music gains greater and greater tensino as the musicians turn and twist their way into even smaller spirals, right on up to the end of the movement. The second movement, Stasis, offers a peaceful, angelic repose as it gently unwinds the pressure that has been built up by the two instrumentalists. Torque was commissioned by the Barlow Endowment for violist Viacheslav Dinerchtein.
