Thanks Matt and Vesuvio!!
As for tone: I am not yet really sure how to get the best sound for the high melody notes
Rest stroke doesnt work, cause its dampening the open b string. And no matter how hard I try, my free stroke wont sound like a rest stroke.
Then I have to work on a more consistent speed, and get rid of the erratic changes in tone color and loudness.
I think I'll post an update sooner or later.
