Going back to the link between standing and singing...
Sitting down is a massive imepdement to loud, consistent singing and you'll never get a genuinely good, noisey atmosphere without everybody standing. Everybody who regularly goes to football matches, stands and sings already knows this to be true, but I've seen it disputed by people on the caf. "Why do you have to stand, why can't you just sing anyway" etc.
Well, I witnessed an interesting parallel last night...
I went to see a gig by a band who I've seen two or three times before, and whose songs are big sing-alongs. Although the band do well crafted harmonies, with three members singing etc, they are also quite a "good time" band live, and positively encourage everybody to sing along, holding the mic to the crowd for chorus lines etc. On previous occasions, in standing venues, nobody would hesitate to bellow those chorus lines back to the band, totally unconcerned about our own lack of vocal ability etc.
However, last night's gig was an all-seated affair, billed as an acoustic gig. in reality, it was far from acoustic - electric bass, keyboards, amplified guitar and vocals - the drummer using those brush-drumsticks was about the only concession to keeping things marginally quieter than ususal. But the whole seating thing made it feel very different - better in some ways, as you could really take in what the band were doing and appreciate their talent - but a whole lot more reserved, with relatively polite clapping when they came on etc.
And when it came to the first of those big sing-along lines, the lead singer stopped, waiting for the crowd to take over, only for their to be a murmered, under-the-breath response form the crowd. The singer gave us a jokey "Hey, it's OK to sing along!", and next time round there was slightly more response, but it was nothing like what I'd experienced at other gigs. Ultimately, people just didn't feel able to bellow the lines out while sitting down. I tried my best, but felt suddenly self-conscious in a way I never have in a standing gig, despite having had a couple of pints.
My guess it's that it's a combination of a couple of factors:
1. It's physically hard to sing at full volume while seated. This is why every band or singer you've ever seen (other than the most gentle piano-crooner) and every choir and every bloke at the top of a mosque doing the call to prayer stands up. It's some pretty basic stuff to do with your lungs and that.
2. Sitting down immediately instills a different set of social norms. We associate it with watching a play, being in a classroom or a church (in which, when it's time to sing, everybody stands up) etc. We are brought up to know that you sit down to listen / observe and you should make minimal noise while doing so.
Anyway, as I say, none of this is anything we didn't already know, but I did find the experience of the gig interesting (it was very good by the way).
