On the Resonant Frequency in the Way of Un-Legato
XU Bi-ha · 2010
Just like the human being sound principles,both the sounding substance and the resonant frequency in the sounding are depended on the timbre.Based on researching a great number of piano acoustic document both at home and abroad,the auther got the known proposition that the different touch skills can make the piano resonating body changing result,sounding in variety timbres.Selected the skill of non legato,respresented the characteristic of metal timbre on piano in three basic playing techniques,as research object,through the software of VOICEBOX,The MATLAB toolbox for speech processing,by sampling and cutting contrastive analysis both of the same with different playing touch ways on KAWAI upright piano,proved the known proposition with the physical quantity and the trend line graph,the auther explored the influence on resonant frequency by different touch key in non legato playing.
