All the medical literature suggests that singing will help. My husband's voice is muffled from the Parkinson's but he continues to sing in the shower. I think it has improved his voice to a small degree, but more importantly, it lifts his mood. Go sing in the shower!

It has taken a major joy out of my life.

I seem to have lost my ability to stay on key, but I still try to belt out songs in the car - it helps with volume, and after awhile, my ability to sing improves. Another use it or lose it, maybe.

I have noticed that my voice is very different, tight and without ability to fluctuate sounds. Definitely unable to sing.

how did you manage to sing in sheets of paper-quires- or did you mean choirs lol
