Originally, the symphonium was part of a fantastic production chain, which produced music. It's been the the place where beats, melodies and sounds were assembled to music.

The right side of the preview displays a view of said game. I've lost the version in the original colors though, and the version that I kept has the stronger colors as shown to the left.

While it's unlikely that another game needs an industry chain to produce music, it still might be usable as a sci-fi technical element, be it a power plant, radar station, or fancy processing plant.
