I would like to know more in detail what the approach would be in executing tremolo. Do you do only 4-finger tremolo when training? Did you leave the thumb inactive while executing i a m i or did you always use the thumb before the first i ?.

I'm trying to find out how long it takes to get a good steady flow of tremolo going with confidence on at least four strings.

I have a minor case of focal dystonia that causes me some problem with my index finger, and I'm trying to figure out if I will ever do tremolo correctly. As I said before, no teacher has ever mentioned how long it takes the average student to execute 3- or 4-finger tremolo smoothly. I don't think it took you 3 years just for the tremolo part itself.
