Map Set 8 is a stereo sound piece that is based on the map of the human genome which was first published in the journal Science in February, 2001.
Frequencies of the four bases of DNA (GATC) are reproduced by a human voice. A stereo delay mimics the feeling of heterodyning as it was experienced during the process of reproducing the frequencies using headphones to monitor the accuracy of the pitch being sung. The score consists of the first 14 megabases of chromosome #1, the very beginning of the map.
