Yiran Zhao makes use not only of musical elements but also of objects, bodies, movements and light-sources as compositional material. Many of her pieces inhabit the various boundary states between instrumental music, performance, sound-installation, and video-art. Leonie Reineke describes the composer in the booklet as a Inchprudent researcherInch, who encounters the sonic cosmos of her environment with great earnestness, and comes microscopically close to things. In the composition InchPiepInch she focuses on electrical metronomes as sound generators, with which the two percussionists Christian Dierstein and Dirk Rothbrust produce rhythmic patterns, different pitches or glissandi. In InchFluctuation IaInch, interpreted by Ensemble Recherche, the entire development of the music derives from a cookie-tin hanging from a stand, connected by a metal wire to a piano string. As a starting point for the contemporary melodrama InchOder Ekel kommt vor EssenzInch Zhao analyzed with the computer a poetry collection of the Congolese Fiston Mwanza Mujila. The Deutsche-Symphonie Orchester Berlin can be heard here sometimes with full, saturated orchestral sound, sometimes speechlike in the instruments' articulation. Towards the end the piece is leaving the stage free for a powerful text recitation of the poet himself. Four additional videos, which are only available online, complement the six instrumental-vocal works of this portrait. Zhao's virtuoso use of light can be experienced in the work InchOhne Stille IIInch for example.
