This article suggests that singing is good for you. Even if you aren’t a great singer or, heck, even if you sing like I do!
I sometimes ask my students if they sing. The majority tell me they never sing. I’m sorry to see singing disappear like that. We all sang when I was in elementary school; we even had music books that we used back then. I sang in church. I sang with my friends. I even sang with my family in the car. When our children were babies I created little songs that included their names and sang those to them. I don’t have a great voice. I don’t even have a good voice. But I like to sing. Give it a go sometime … it might be good for you!
