My name is Richard. I am an absolute beginner to harmonica, though I play piano. Does it matter which hand I use to hold the harmonica? Secondly, what type of physical, meaning pulmonary/cardiac condition does a harmonica player need to have? Thank you.

Hey Richard - welcome to the forum! At the beginning it doesn’t matter what hand you use to play the harmonica. As you progress, you will learn the cup grip where you hold it with your left hand and cup over your left hand and the harp with your right hand. But for now, don’t even worry.

I would start here.

Regarding your second question, whatever kind of health your in, harmonica will be good for your health! And vice-versa, the better your lungs are, the easier some things will be on the harmonica.

Hope that helps!
