星期六上课的时候,陈老师说我的琴头有点低,让我注意改正。下课回家的路上,妈妈就给我下了任务:这星期必须改正。有什么办法不让我的琴头低呢?我每天都照着镜子练琴,还让爸爸妈妈监督我,妈妈还帮我想了一个好方法,把谱架升到琴头的高度,我练琴的时候只要琴头碰上谱架,我就马上? When class saturday saturday, my teacher said my head was a bit low, let me pay attention to correct it. On the way home after class, my mother gave me the task: this week must be corrected. Is there any way to keep my head low? Every day, I practice in a mirror and let my father and mother supervise me. My mother also helped me think of a good way to raise the music stand to the height of the head. As long as the piano head hit the music stand, I’ll be right?
