英文嘛，無問題。全文打出如下，用網上翻譯應可以了解大約內容。之前的數字是播出的時間。
0:08 - Vibrato, a shaking of the arm and hand adds a lot of warmth to your playing.
0:14 - Basically, a vibrato is playing the note in tune, and then rolling the finger slightly flat.
0:21 - To do it sucessfully, you have to have what is called a two-point contact.
Let's look at this up close.
0:28 - There are three types of vibrato, there is a finger vibrato;there is a wrist vibrato, and then an arm vibrato, which is preferredby blue grass players.
0:39 - Standard fiddle playing calls for three-point contact. Thefirst knuckle touching the side of the neck, the thumb coming around,and positions itself on the opposite side. And then the fingercurls around and push it down on the string. One-two-three.
0:56 - If you hold a violin like that, it's okay to play notes, but itis very difficult to vibrato. You need to do a two-pointcontact. Where just the thumb, preferrably on the bottom, and thefinger, freeing up the side of the hand, where the knuckle is to allowit to move back and forth, creating a vibrato.
1:16 - On page 40 of Filldle Volume One, on the excercise I have an Fsharp note played with the second finger. I'll play the note intune, and then push my arm away slightly, see that. What thatdoes is causes the second finger to roll back and go out of tune.
1:38 - Now when it's slow like that, it doesn't sound like a whole lot. But with little more speed, it sounds really nice.
1:51 - Now I am not doing this, I am not bending the wrist up anddown. I am keeping the wrist and the arm rather straight but I ampushing the arm away from me. Doing a nice arm vibrato making itvery warm.
2:08 - The hardest part, probably, I would consider in vibrato iscoordinating the bow stroke with the vibrato. Try it firstwithout using the bow, just practice, say, on 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.
2:30 - You may want to try some excercise where you just hold your armin front of you, and push it away and back, away and back. See Ikeep that steady? That's the motion. You got to get thefeel of going back and forth.
2:43 - The note is in tune, and flat, in tune, and flat. Just like that.
另外Vibrato（揉弦）是應該正音>降音>正音>降音>正音...的去。Ivan Galamian是如此提倡。
