Great Polka Sound (2006) was an attempt to create music using GPS information.

I was wandering through a park while a GPS reciever continuously collected information about longtitude, latitude and altitude of my position, and saved them into a text file. Processing was used to to visualize the data, and to send it via OpenSoundControl to Max MSP, which converted the information into MIDI signals. Position and travelling speed changed pitch and length of the tones.

The generated melody plays over a raw song structure, typical for the German genre 'Heimatmusik' ("homeland music"). Consequently, the homeland created the melody.
