Sonare and Celare, the two string quartets by Turkish-born composer Cenk Ergün (b. 1978) released together on an EP, are complementary works in many senses of the word. Originally conceived of as a single piece, the two quartets instead became companion pieces whose sonic qualities are creatively opposed to one another. As is often the case when Ergün composes acoustic works, these two quartets of 2015-2016were the product of a collaborative process. In sketching and then finalizing them, Ergün worked closely with the JACK Quartet, for whom they were written.
Sonare was composed through an elaborate process of reverse-engineering: Ergün first set out rhythm patterns using the MAX program and then densified their textures through software-facilitated combination. The JACK Quartet recorded a number of rehearsals of the resulting material, which Ergün edited into a sort of master take that he then transcribed and notated for the final score. As one might expect from a process like that, Sonare is a composition of dense textures. It opens with a thick, aggressive sound evoking an asynchronous, loudly buzzing swarm of insects. A close listen, though, reveals the mass to be made up of the pulsing accents of individual bowings. The piece develops as a set of variations not only on dynamics—first very loud, then very soft, then back again to full fury—but on bow speeds as well. Pitch seems to be a secondary element—a necessary yet epiphenomenal component of mass.
Celare, by contrast, is a symmetrical three-part work whose first and third sections feature short, widely spaced bowed and plucked sound events played at low volume. The middle section of the work, which consists of a drone of microtonally spaced intervals, recalls Sonare’s buzzing dissonance but lays it out in a gradually shifting layers and steady, mid-range dynamics. Celare seems to take Sonare’s volumetric sound blocks and thin them out, retaining the latter’s microtonality and fusion of voices while dispersing them through a structural substitution of space for mass.
The JACK Quartet plays these complementary pieces with the finely calibrated degrees of energy and delicacy they call for.
