Haha, the 'not succeeding to sing out of tune' quote is wonderful!
Your first comment got me thinking. I wonder about the extent to which band musicians learn to develop and sustain a 'performance act' which is out of character to their 'off-stage' personalities. And the extent to which live music performances truly 'inspire and energize' musicians to perform out of their (off-stage) 'comfort zones'.
Regarding the 1st factor, I recently watched an interview with
Alice Cooper on
BBC Breakfast in which he said that his public persona and all his performances were all just an 'act'. Which was very far removed from his true personality and beliefs.
FWIW, I've noticed the 2nd factor too. I'm a quiet, introverted person who hates crowds, social receptions, etc. I feel much more comfortable (occasionally) blending in with small groups of 2-5 people. Even in 'Big Band' performances, individual players' performances are fairly anonymous. Except for occasional brief solos.
But since joining a Pop/Rock band 2 years ago (aged 70!), something changed. I started to really enjoy rehearsing and playing as 'the sax player'. Now, with a fellow trumpet player it's even more fun. The 'beat' just keeps me moving around - even when I'm not playing. And somehow the 'horn section' bits inspire en energize me to reflect these in body/head movements, etc. This is not acting or rehearsed. It's just a purely spontaneous (physical) response to 'the music'.
So, for me, rehearsing and performing music that I love listening to (when I'm not playing) and love contributing to does truly 'energize' me!
