In Meditation #2, we were directed to make a musical piece that recreates a random "walking tour" of the Seven Bridges of Königsberg. In my piece, each island and bridge is treated as a separate node and each node is associated with a note. The notes are played in quick succession—around 20 per second—and have a long decay time. The idea was to create something that illustrates the structure of the graph, something architectural: a wash that contains many events, but appears to move slowly (or not at all).
This Python script generated the score and this csound file generates the output (includes some sample score data). You can play a sample run of the program (1200 steps, about 0:55) below (or download it here).
