Talking with Elvis Costello in the steam-room about the difference between scored and played music. When music is generated by a group of people playing, everyone tends to play most of the time. With scoring, you’re likely to use instruments when you need them. No one feels bad about standing round for three-quarters of an hour and then going ‘bong’ on a timp if that’s what the score demands. This is why scored music is more ‘colouristic’ and contoured than most pop – whole sections come and go; the dynamic and timbral ranges are very broad.
