海飛茲(Heifetz)2-Debussy 亞麻色頭發的少女+Dinicu 霍拉舞曲

霍拉舞曲 was often broadcasted in china, here i hardly ever hear it played anywhere. People think of it as circus music.

I think that was the wrong impression because of the different camera angle.

琴弓應和琴弦成９０度垂直，這似乎應該成了小提琴裏的一條定律。
觀海氏霍拉舞曲的下行連頓弓，行至弓尖處，弓弦連４５度都到不了。且每次下行連頓弓都是如此，顯然是有意為之，故意把弓往懷裏“拽”。
各位高手有何高見？這是提琴教科書（下行連頓弓）的標準做法嗎？
