I have recently come up with the idea of composing music according to maps. I arrived at this conclusion through my interest in becoming more familiar with the geography of both my local region and the world in its entirety. To be more specific, I will be using maps to measure phrase length, cadences and key centers according to altitude, mileage, curvature of roads etc. My question for you is: What other interesting inspirations have you come across? Are there some particular impetuses that stand out for you? We can share different reasons for making music and literature, something which might not be so obvious or common place.
