The way the book is presented, I was hoping to get some explanations, or maybe even a solution about how to change anybody in a decent singer. Alas, no. You get huge lists of names, this person who worked for the Beatles, this one for the Clash, etc, and they have all turned into music teachers for bad singers.
You are promised revelations about the way the brain deals with music, I'm still looking for them.
Finally, the author sang two songs in front of 35 persons, after years of training. Were the songs well sung? I don't know...
I belong to the people who cannot sing. I've always known it, since I was 6 or 7, meaning when you can hear the difference, I know a couple of things, like the importance of paroles which make it easier to be in a decent pitch. Surprisingly, the author hardly speaks of it. I gave up around 10. If it is impossible, no use spending so much energy for no results.
I hoped finding some answers here, but sadly, nothing.
