Jim makes a good point about adjusting your technique to different situations. I'm sure most of us adapt the volume and probably the style from when we're singing in a big, noisy room to when we're at home in the living room or in a caravan awning at a festival in the early hours (sorry to anyone we've kept awake).

One situation where both mrsleveller and I have had to think about our technique is when using microphones. Neither of us had had much experience of this until recently and we had to learn to adopt a more intimate approach rather than belting it out. I wonder how many younger singers have developed their style for microphone use and find it harder to project without it.
