I’m not sure if this is the correct place to post this but I think it is.
Last year I had a stroke and I can’t use my left arm very easily. Can I learn to play harmonica with only my right arm/hand?
My mouth is fine. My right side is fully functional. Most instruments require both hands but the harmonica, being a mouth based instrument, looks doable,
@barronsnyder this is definitely possible. Just look at guitarists who play harmonica at the same time: they use both hands to play the guitar.
Hi @barronsnyder, and welcome to the forum. Yes, you most certainly can play one handed. Left-handed is more common, but there’s no reason why you can’t play right-handed. Others can instruct you much better than I can, and I’m sure they will. The people on this forum are generally very kind and helpful. I hope you go for it and come to love it. Have you played other musical instruments?
Welcome! I teach all my students to hold the harp in one hand. You are good.
Shouldn’t be a problem. Most of the manipulation you can use your head for, unless your big into using massive note jumps from say holes 1 over to 9 or 10.
I wish you a continued recovery!
@barronsnyder Welcome to the forum! I love playing harmonica while I walk, and I switch between my left and right hand. Welcome to the forum!! You got this! 
I will add one more thought to make sure you are covered and nothing creeps in to give you pause. I’m trying to think of a single instrument that “requires” two hands. I met a one armed ukulele player, I knew two left handed piano players. Many instruments allow two hands and offer an option for two hands, or 2 feet as the case may be. But again, I can’t think of an instrument that “requires” two hands. Certainly using one hand on an instrument that offers options for using two is going to be limiting. But I have two hands and still i’m incredibly limited. And I’m fine with that because I understand it’s my limitations that make me unique and it is our uniqueness that is the great gift to ourselves and others. Welcome to the club! Corky
You can definitely play with only your right hand. I learned to play while driving using only my right hand (for obvious reasons) listening to a Jon Gindick CD.
I watched the video of the 12 students playing the Boogie tune-it sounds fantastic! Eventually life is going to slow down and I will have more time to playing on a consistent basis…but in the meantime I am curious, why do you teach your students to hold the harp with one hand?
@1bakingblackdog It’s better for posture, relaxation and breathing.
Everything is easier. It’s really that simple.
Thank you to you both for responding to my question. I found that although I am predominantly right handed I am much more comfortable holding a harp in my left hand. I tried holding a harp in my right and found I had more control and accuracy when using my left. Our brain body connections are so interesting!
