The original idea behind this track was to process an autoharp with a bit of delay. It ended up being heavily modulated delay and if you listen closely you can sometimes hear a bit of autoharp... them's the breaks! The modulating delay lines reminded me of contours on a map - hence the title. Also a tribute to some of the great abstract titles of 70s and 80s electronic music like "Correlations" and "Pinnacles".
