Answer: It's G, D, A, E.
Explanation: So from left, lowest string, G to high string E. And there are YT videos that could help you on how to learn the violin. Or I suggest getting the Essential Elements books for Violin. It is able to guide you through notes, rhythm, etc. That's how I was able to learn the violin with my private teacher, and still in orchestra to this day. Maybe try going over a few numbers everyday till you can nail it, then continue on to the next ones. Good luck!
