目前我们正处于一个世界性的音律变革时代,音律问题是一个比较深奥但又必须加以学习的课题。学习音律的第一课音阶不是一种,而有好几种,它是以数学为基础的,这种数学基础就是音律。如钢琴、电子琴等用的是十二平均律,十二平均律是将2开12次方计算出来的,它的12个半音完全相等;但与声乐、管弦所用的音阶却是不同的。你要是留心仔细地去听,就会发现它们的音高与你心中所想的音高有着微小的差距。这是学习音律的第一课。关于纯律音阶从上世纪40年代起,西方各国逐步地改用了纯 At present, we are in a world era of musical change, and the issue of temperament is a more esoteric subject that must be studied. The first lesson of learning temperament scale is not a species, there are several, it is based on mathematics, this mathematical basis is the temperament. Such as the piano, keyboard and so on are twelve average law, twelve average law is 2 to 12 times the square out of its 12 semitones exactly the same; but with vocals, orchestration is different. If you look carefully and listen carefully, you will find that there is a slight difference between their pitch and the pitch you think. This is the first lesson to learn about temperament. About the pure rhythm Since the 1940s, Western countries gradually switched to pure
