This is probably a dumb question but I’m horribly ignorant to the rules of tipping. (I never thought to tip a pizza delivery person until within the last few years.) Anyway, I’m planning to start with guitar lessons soon. In America, does proper etiquette necessitate tipping this person?
Please note, I’m really not looking for a discussion on the inherent rightness or wrongness of tipping. That’s been done to death already. 
Other than a gift at the holidays, I have never tipped a music instructor. I don’t believe that is expected.
Not really a tipping situation. Maybe a holiday gift but only if you get on well.
My daughter took guitar lessons, mandolin lessons, and voice lessons. We never tipped.
I took private classical flute lessons for a number of years, and I never tipped my instructor. There was usually a small Christmas gift, but no tips.
Christmas gift? Yes. Tip? No.
Yes please 
Definitely not. Tipping instructors of any kind is not expected, in my experience.
We gave our piano teacher a gift each Christmas, and occasionally a small token of appreciation if my sister or I passed a Royal Conservatory exam with flying colours.
Thanks for the replies.
I was never tipped when I had a studio. I did receive Christmas gifts but not tips.
BTW my biggest gripe was people “forgetting” to bring their checks to pay me. GRRRR.
We paid before every lesson directly to the instructor. Nobody paid the guy a tip. It’s a cash up front payment to the person that instructs you. I guess you might if they went way beyond normal in training you on a day.
I’m a guitar teacher. I have never received a tip of any kind, ever.
No tip.
