音高是音乐中最基本的成份之一。无论在传统音乐还是电脑音乐中,都有着许多围绕音高的话题。 物理学用每秒的振动次数表示音高,人耳能够感受到的音高范围大致在每秒20次到2万次振动之间,所有的音乐当然也不可能超出这个范围。音乐界习惯用音名和唱名表示音高,因此首先要碰到—个标准音的问题。ABC也好,DoReMi也好,都得有个共同的标准,不然就成“一人一把号,各吹各的调”了。我们现在通用的以每秒440次振动为A的标准音,是1834
Pitch is one of the most basic components of music. There are many topics around pitch in both traditional music and computer music. Physics speaks pitches in terms of the number of vibrations per second, and the range of pitches the human ear can perceive is roughly between 20 and 20,000 vibrations per second, all of which, of course, can not exceed this range. The music industry is accustomed to using tone names and roll names to express pitch, so first of all, you have to meet - a standard question. ABC Ye Hao, DoReMi Ye Hao, have to have a common standard, otherwise it becomes “a number one person, each blowing all the tune.” We are now common to 440 times per second vibration A standard sound is 1834
