Ivan, it is a fact that singing surpasses many vocal problems. Stuttering, shyness. Also music is the one thing that most people retain in their memory, when everything seems to be gone. I have had patients remember, word for word and harmony , songs from their past, when they were unable to remember ANYTHING else. I had one that seldom spoke anything but gibberish .If I would sing she would sing with me ,quite well, too.Even after she no longer remembered the words she for a long time was still able to hum and harmonize,on pitch. So stick with the music. It is not only wonderfulfilling, it is good therapy. Enjoy. Do well! Juanita CG for George 74/71/64
