String Quartet No. 2 “For AFC System”

2021

About the Work

Composed in 2021 for Yamaha's AFC (Active Field Control) system as part of a joint research project with Dr. Sungyoung Kim (Rochester Institute of Technology). Treating the AFC system as an instrument fused with the string quartet, the piece builds four reverberation patterns in space (AFC Enhance) while surround effects envelop the audience (AFC Image). Two contrasting sections unfold toward a climax, driven by a main theme of repeated short notes that make the room's reverberation tangible to the listener.
