| 摘 要： | 根据弦振驻波的规律,证明了弦乐器振动中各次振动的振幅递减之规律,给出了演奏中准确的泛音触弦位置,揭示了拉弦类乐器泛音的物理本质,是设计扩展音域、增加自然泛音的理论根据。

| Abstract: | According to the law of the string vibration standing wave,we have proven the rule that each vibration oscillation amplitude of the stringed musical instrument decreases progressively.The accurate overtone string position during the performance was also given.The overtone physical essence of bowed instrument was revealed.It's the theoretic basis for designing the sound territory and strengthening the natural overtone. |
| |
| Keywords: | standing wave pitch overtone sound territory harmonic function |
