Yes, many. I started piano lessons when I was 9. I kept them up all through school and into college. In college I had to have a secondary instrument, so I took voice lessons. Five years ago I started fiddle lessons.

I have never had any guitar lessons, but since I've been fiddling, the guitar makes a lot more sense.

When I studied piano, it was all classical music, of course. I had some "jazz" lessons in college but didn't really like it much. All of my popular stuff, I have always learned by ear. Never bought sheet music except to get the words.

Fiddling is about 50/50. I learn a lot from printed music, but a lot by ear as well.

It never hurts to take a few lessons just to expand your knowledge. Most teachers will be willing to coach you, without you having to make a full-time commitment to weekly lessons, unless that's what you want to do.
