Hi Ivan
I wrote in Muris' room about the helping you both gave me.
So it is also fair to write in your forum.

Well, my vibrato is going better and my movements are less seized. I'm moving more my wrist with less strength, it's a slow vibrato but more controled, so I think is going fine.
By the way I have problems when I bend and do a vibrato. The sound fade out after 2 or 3 motions, I think this is because I release some pressure during the motion. Practice practice practice.
And also when I bend sometimes (almost always ) the upper strings that I'm moving when I bend the lower string sound too. Any technique to avoid that "extra" sound?
Thanks!!!
