| contents | The lowest notes produced by string instruments are typically limited by the fundamental vibration of the strings. However, precise control of bow pressure can lead to the production of even lower notes. Despite significant interest in this counterintuitive technique and various proposed explanations, no conclusive evidence has been provided, making detailed discussions of the underlying mechanism challenging. In this study, we employ high-speed imaging to visualize the spatial vibration modes of stringed instruments, confirming Helmholtz motion and its modifications under subharmonic conditions. Finite element simulations further demonstrated that increased bow pressure amplifies frictional forces, suppressing standard vibrations and allowing subharmonic frequencies to emerge. Our results provide the clear experimental validation of the mechanism underlying subharmonic sound production, providing an avenue for further exploration of vibrational and oscillatory phenomena. |
