为何在小提琴弓弦上擦松香

为何在小提琴弓弦上擦松香

     小提琴的弓毛采用马尾的毛制造而成，质地光滑。小提琴的琴弦由纤维或者金属制成，质地也比较光滑。而小提琴发声的原理，是依靠振动，振动的产生依靠摩擦。但是，上述两样光滑的物体相接处，如何能增的摩擦而使小提琴发出声音呢？那么，就需要松香。松香在外表上看是一大块一大块的，但实际上涂抹后的效果是一小粒一小粒。涂抹松香，就使得弓毛不再光华，而是表面凹凸不平（肉眼无法观测），如此一来，弓毛与琴弦摩擦增大，自然就有声音了。

ORO brunch

It's been a while not to have luxiorios breakfast (costs over 220NTD each p). Abby's insist encourages us to give it a try. Food is okay,but still hard to relax taking Abby with us.It's predictable that Ethan's being distracted (from doing his music work) and Abby's nonstop whining.
