Thanks for sharing that Bryan! I think it’s actually quite common. To some degree that impacted me too when I first started recording music way back. I had no vocal training when I got the Fostex X-15 and started writing and recording songs and recording covers. I’d only sing, or even do any of the recording really, when I was alone. It was much easier to focus, and to not have the fear of some judgement of the performance.
Fear of public speaking is a huge one for many people, right behind fear of falling to your death (I think). So to step up and make any progress on that one is huge for most people.
I figure part of the singing phobia has a lot to do with how public broadcasting and record company artists have featured so many great performers over the last ~100 years or so. It sets a high bar, and our fellow humans tend to judge anything that’s not up to the standards that their mind has been conditioned to accept as ‘professional’. This has even become entrenched with shows like American Idol and The Voice. If you try to sing, you’ll be judged and voted upon. Yuk!
In my experience working with a voice coach, I became very aware of all of this and learning to break through personal boundaries. Working with someone who understands the vocal challenges and insecurities, and who builds your confidence through progressive accomplishment, can make a huge difference.
