This project demonstrates a method for artificially manipulating acoustic piano resonance through real-time sound filtering and reproduction using a soundboard-mounted shaker. Various filters are applied to shape the harmonic and timbral characteristics of the instrument, which are then reproduced through vibrations in the soundboard. The acoustic and filtered sounds are played simultaneously, allowing listeners to perceive how different filters color the natural resonance of the piano. This investigation focuses on how specific filters alter the tonal quality of the instrument and explores their potential for creative sound manipulation within acoustic contexts.
