>>2638339>>2638353>>2638355harmonica is good for your lungs (commonly suggested physical therapy when recovering from lung problems.)
but anon isn't wrong, some people are sensitive to skin contact with brass, it can also discolor your teeth and a few other things.
i have no idea why anon thinks brass is the only material they make harmonica combs out of though. you can get a harmonica made of anything.
>>2638253you can buy plastic, stainless steel, chromed brass, silver, plastic, wood, and many many other kinds of combs and plates for harmonicas.
even if brass sounds the best to you and your skin is sensitive to it, it doesn't mean you can't practice on a different type and perform with a brass one.
