'Sahaf' is part of the cycle 'Shifting Gravity' in which the Israeli composer, known worldwide for her Mozart adaptation Zaïde/Adama, explores the laws of physics and their physical realization in a playful manner. In 'Sahaf' with its unusual instrumentation, a 'flurry' of selective incidents is increasingly parallelized until all instruments jointly imagine the powerful twirling of an oversized ratchet rattle.
