摘要
与人的发声原理一样,音色决定于发声的内容和声音中的共振频率。研究国内外大量钢琴声学文献,得出不同奏法对钢琴共鸣腔产生不同影响从而产生不同音色的已知命题。在钢琴3种基本弹奏法中,选例最能代表钢琴"金属性"音色特征的非连奏法(non legato)为研究对象,通过"VOICE-BOX,The MATLAB toolboxfor speech processing"软件,在立式"卡瓦依"钢琴上用不同奏法和相同奏法下不同触键方式的采样、切割对比分析,用求得的物理量和趋势线形图对已知命题加以证明,探究非连奏法中触键方式的不同,对共振频率的具体影响。
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.
