Hilary Hahn小提琴演奏《巴赫小夜曲》

The sound of a beautiful round, often by good bowing. So the bow method research is very important, the following points, more it is worth noting that:
1, when the sound at the beginning, will make it very clear and calm. Harsh tone, because the bow hair touch, without proper seize the string, with string. To get the fullness of sound, a beautiful hair bow must choose the appropriate position contact string (presumably ps 1 inch), and make hair bow width all contact with string, bow slightly outward, oblique plate.
2, when the bow in a straight line.
3, all kinds of bowing in forearm and hand. Arm basic motionless.
4, usually with a bow, with equal speed. Uneven tone, will be on a bow with a strong a weak sound, nature is not good.

一个优美圆润的音，常由良好的弓法而来。所以弓法的研究非常重要，下面几点，更值得注意：
1、当音一开始的时候，就要使其非常清脆、平静。恶劣音调的产生，是因为弓毛触弦时，没有适当抓住弦，贴紧弦的缘故。要想得到一个优美丰满的音，弓毛必须选择适当的地位触弦（大概是弓根1寸处），并使弓毛全部阔度与弦接触，弓杆微微向外，斜向指板。
2、拉弓时成直线。
3、各种弓法都只用小臂、手。大臂基本不动。
4、通常用弓，要用均等的速率。不均匀的音调，就会在一弓上发出一强一弱的音，自然不好听。
