The act of singing differs greatly from playing a instrument- the singer, in essence, acts as the instrument. The vocal chords are your strings, your mouth is the horn and the correctness of your pitch is dictated by things like breath control and careful listening.
In some ways singing is far easier than picking up an instrument to play- if you know a song, you can just sing it, albeit incorrectly (at first!), since you already know how to use your voice. In other ways it is far more difficult. You have nothing to hide behind- any mistake in pitch, lyrics, cadence, its all on you.
I mention this because, the more I practice singing, the more I find that I am willing to take risks in rehearsals. Failure is assured at first, but the act of failing is how we learn. I am very much someone who holds back and wants to think their way through a challenge first. But you can’t do that with singing- you need to take a shot, fail, feel what was wrong, dust yourself off and try again. Wash, rinse, repeat.
It’s an odd feeling, simply “going for it” in a voice lesson when you don’t feel ready. But that’s how I improve. I can practice on my own all I want but if no one hears me, critiques, makes suggestions, then I can’t grow, so the real challenge is putting it all out there for others.
This certainly applies to work as well. I am far more willing to simply take a shot at something than I once was. Accepting and acknowledging a small amount of failure is healthy, and is an excellent motivator to improve. Where once I would not have even thought of beginning a project until I understood every nuance in advance I now am able to take a crack at it with a basic explanation and at least get my hands dirty enough to see whether it makes sense or if I need to try it differently.
It’s the difference between saying “yes” where I once would have said “no.”
