It has been interesting weaving the church choir recordings with the different shop sounds together in the score. What is noticeable (at least to me) is the way the different sounds function, in the sense of their psycological effect. In most cases, I do not believe that this is by chance; rather, the sound has been designed that way. The gentle singing of the choir slows the pulse and encourages a reflective state, whereas a washing machine is designed to sound like a trustworthy worker – and the same for a lot of machines that are designed to replace some apparently hard chore: they have to sound like they are saving you from that hard graft! And so the sounds in the installation also say something about why one might want to avail themselves of a particular trade.
