我的母语是汉语好不好,没看我在这个用得这么自如嘛,瑞典语是第三语言,现在只会听和读不会说,哑吧一样。
学英语时听力是我强项,我那1%在错在哪啊?请弦影大歌指教。
市长大人先好好把这个视频看懂,听懂水平就 ...
真的很厉害,我大致改了一下。Check the attachment for detail.
Vibrato, a shaking of the arm and hand adds a lot of work to your playing. Basically, vibrato is playing a note in tune and then rolling the finger slightly flat. To do it successfully, you have to have what's called two point contact. Let's look at this up close. There are three types of vibrato. There's a finger vibrato. There's a wrist vibrato. And then an arm vibrato which is preferred by bluegrass players. Standard fiddle playing calls for a vibrato 3 point contact. The first knuckle touching the side neck, the thumb coming around and position itself is on the opposite side, and then the finger crawls around it pushes down on the string, one, two, three. If you hold the violin like that, it's ok to play notes, but it's very difficult to vibrato. You need to do a two point contact where is just the thumb preferably on the bottom, and the finger freeing up the side of the hand where the knuckle is to allow to move back and forth, creating the vibrato.
On Page 40 of Fiddle Volume One, on the exercise it has an F sharp note playing with the second finger. I'll play the note in tune, and then push my arm away slightly, see that? And what that does it causes the second finger to roll back and go out of tune. Now it is slow like that, doesn't sound like a whole lot, the little more speed sounds really nice. Now, I'm not doing this, I'm not bending the wrist up and down. I'm keeping the wrist and the arm rather straight but I am pushing my hand away from me. Doing a nice arm vibrato makes it really warm.
The hardest part probably I would consider in vibrato is coordinating the bow stroke with the vibrato. Try first without using the bow. Just practice, say as an F sharp note or C sharp or G note, moving your hand away and back, away and back. Be careful not to flop that wrist, keep that from doing that, keep it rather straight.
You may want to try some exercises when you just hold your arm in front of you, push it away and back, away and back, see I keep that sturdy? That's the motion, you gotta get that feel of going back and forth. The note is in tune, then flat, then in tune, then flat, just like that.
