Why would humans have voices if not to use them: Is your voice recognizable? Probably, as it is now used for identification purposes. What if you are a singer? Will you allow an opera director to require that you sound like someone else?
Here I am: a pianist. My “voice” resides in my fingertips. To what extent is my playing responded to because my voice is unique? How often has it been rejected because it does not match other pianistic products (let’s not call those “voices.”) I was once advised by Miecyszlaw Horszowski that people would try to “fix” my voice. “Don’t let anybody change it.”
