能否把一架钢琴的音调准,关键在于对中音区的十二平均律分解。传统调平均律的办法是:先把橡皮(或毛毡)止音楔插入a~1音的左右两边,只让中间一根弦发音,并使它和标准音叉(A)的音高相同。接着再去掉左右两边的止音楔,以中间一根弦为准,把边上的两根弦也相继调准。在调好a~1音之后,就以a~1为准调下方八度的a。当a的三根弦调准后由a调e~1,再由e~1调b……,直到分完这一组的十二平均律为止。全部程序所使用的方法都一样:总是先调中间一根,再调边上两根。但是,这种传统的方法,只适用于已有相当把握的专业调律人员;而对初学者或调
The key to adjusting the pitch of a piano lies in the resolution of the twelve-law average of the midrange area. The traditional method of leveling a law is to first insert the rubber (or felt) stopwatch wedge into the left and right of the a-1 sound, making only the middle string sound and making it the same pitch as the standard tuning fork (A). Then remove the left and right sides of the stop wedge to the middle of a string prevail, the edge of the two strings have also been adjusted. After adjusting a ~ 1 tone, adjust the octave below a to a. When a of the three strings aligned by a tone e ~ 1, then by e ~ 1 transfer b ... ... until the end of this group until the twelve average law. All the methods used by the program are the same: always adjust the middle one, then adjust the edge of the two. However, this traditional method is only applicable to professional lawyers who are already fairly confident;
