"Sound of Cities" is an interactive musical program exploring the boundary between a video game and a musical instrument. The inspiration comes from the construction system that many games have. The main objective is to make a program that combines sandbox construction and interactive audio, or it can be said to create an "audio sandbox". Each building corresponds to a timbre. Every building is a sound emitter.
There is a metronome in the UI below. Players can adjust the pitch of each building themselves in Edit mode, and also change the timing of each sound. While players are building cities, they are also creating music simultaneously. There is a character as the listener. The volume of each building decreases with distance, so the music can be changed interactively by moving the character.
