我们在欣赏音乐的时候,不但会陶醉在歌唱家美妙的歌声中,也会陶醉在各种管弦乐器所发出的美妙音符中。管弦乐器是怎样发出各种不同频率的声音的呢?我们知道,乐音有音调、音色和响度三要素。其中,音调即基音频率的高低;音色(音品)决定于泛音的分布、组成以及强弱;响度则与振动的强弱有关,体现为声音的大小。不同的乐器发同一个音时,音调相同,但音色不同。对于弦乐器,如二胡、小提琴、古筝等是依靠弦的振动而发声的。弦的振动频率不同,我们也就听到了不同频率的声音。那么,弦的振动频率与哪
When we enjoy music, we not only revel in the singer’s wonderful song, but also marvel at the wonderful notes made by various orchestral instruments. How do the orchestral instruments emit sounds of different frequencies? We know that there are three elements of tone, tone and loudness. Among them, the tone is the pitch of the pitch frequency; tone (tone) depends on the harmonic distribution, composition and strength; loudness and the strength of the vibration, reflected in the size of the sound. When different instruments make the same sound, they have the same pitch but different tones. For stringed instruments, such as erhu, violin, guzheng, etc. rely on the vibration of the string and sound. The vibration frequency of the string is different, we also hear the sound of different frequencies. So, where is the vibration frequency of the string?
