In the Chronolith installation, the Jata C group explores the sonority of stone structures, symbols of permanence, immensity, and silence. Like rocks are the Earth’s membrane, the Chronolith is an instrument/membrane that helps us translate the vibrations of the stones with transducers and return them to the rocks in a feedback loop. The sound installation is composed of several large stone plates connected to transducers. The installation may be set up alone or in a concert setting whereby the group members are inserted into the feedback loop between stones and humans. In the research process, the group collaborates with scientists from the fields of micropaleontology, geology, and physics. The project is supported by Marmor Hotavlje. In addition to sounds of stones captured by various field recording devices ( geophones, contact microphones), the sound is also generated from images (spectral analysis of optical rock scans by sound modulator). The processed recordings and databases are used in electroacoustic composition with a score for live performance. The group creates an original artistic interpretation of the lithosphere’s material sonority through digital analysis and the translation of images into sound and vibration measurements.
