Can we create music out of architecture?
I've been wondering this ever since I became interested in architecture during high school. I'd walk past sky scrapers in New York and wonder if you could fly a helicopter over it, then turn the entire city into a series of notes.
Inspired by the theramin, I wondered if you could shoot a beam down from a helicopter and get a frequency back based on distance.
I eventually realized that using the tallest building as a reference point was probably not the best way to get a diverse range of sounds, so I switched to taking the ratio of each building's height and the median building height.
