Analysis of Pitch Perception of Inharmonicity in Pipa Strings Using Response Surface Methodology
Shin-Hui Lin Chin, Jonathan C Berger · Journal of New Music Research · 2010
The timbre of the pipa, one of the principal plucked string instruments of traditional Chinese music, is characterized by richly nuanced inharmonicity resulting from peculiarities of regionally distinct string composition and construction. This study investigates the effect of this feature of timbre on pitch perception. Beyond the specific issue of the pipa, we propose a response surface based experimental design and modelling approach as a general framework for determining the effect of inharmonicity on pitch perception applicable to any stringed instrument.
