I started re-learning a few months ago after a 41 year hiatus and my program goes something like this:
First step: Buy violin (a cheap one)… and later on purchased a good one (Damiano)
2nd step: Downloaded some etude books and tried them out
3rd step: when I could somewhat play the etudes I started jamming with some friends
4th step: Came to websites like this one and started learning properly
5th step: Hired a private teacher
And during this whole process…. practice, practice, practice and have not given up.
