有的学校,由于设备较差,没有键盘乐器,甚至连一支笛子也没有,因此音乐课教唱新歌时,只好由教师起音,常常不是起音定调偏高,就是偏低,使学生跟唱发生困难;起高了唱不上去低了,又发不出声来。这种情况在农村的一些中、小学里是屡见不鲜的。为了解决这个问题,这里介绍一种简易的定调方法。歌曲的曲调虽然千变万化,但常用调却只有那么几个;各调的音域,又都有一定限度。如果音乐教师事前找个有键盘乐器的地方,在琴上弄清楚和记住自己能够自如地唱出的最低音和最高音的音名。那么,从这里推算并唱出中央C音来,便相当容易。
Some schools, due to poor equipment, no keyboard instrument, or even a flute, so music lessons to sing new songs, had to be played by teachers, often not the tone of the tone is high, is low, so that students Difficulty with singing; can not stand up from high to low, unable to send sound. In some rural areas, primary and secondary schools are not uncommon. In order to solve this problem, here is a simple way to adjust. Although the song’s melody is ever-changing, but only a few commonly used tune; tone range, have a certain limit. If the music teacher finds a place with a keyboard instrument beforehand, make clear and remember the bass and treble tones you can freely sing on the piano. Well, it is quite easy to deduce and sing the central C from here.
