"In Zagar’s musical language there is a characteristic attempt at a synthesis of traditional ideals of composition with modern testimonial values. He subjects his compositional premises, which are frequently derived from works of older style periods, to transformations; when this “double logic” is applied, the result is a work which may be understood as a modern commentary on a stabilised cultural value. The starting point for this may be a minimalist form (music for video), a Brahmsian concept of chamber music (Trio for Viola, Cello and Piano), or a traditional form of Christian musical culture (Stabat mater; Pater noster; Apocalypsis Iohannis). Zagar’s works do not bring polystylistic principles to the forefront; rather there is a synthetic purpose, bridging premises that were originally conflicting."
