Piano Migration V was developed by Ivan Franco and Kathy Hinde during the N.I.P. residency, in the amazingly beautiful Montemor-o-Novo.
Naturally site-specific works emerged from the fusion of computer systems for new media and the ecological surrounding. By observing the resting of birds on telegraph lines, it was soon obvious how much the lines resembled a music score or piano roll. Thus, a computer-vision program was developed in order to scan a video of the birds behaviour to translate it into music, by triggering audio sample of a prepared piano in the same fashion as a modern step-sequencer.
The prepared piano samples were generated by placing nuts, bolts, and pieces of rubber between piano strings to create a different sound-world and tuning system to a regular piano.”
