Each of the standard eight virtue Cities use this music including Britain, Skara Brae, Trinsic, Jhelom, Magincia, Moonglow, Minoc, Yew. Oddly enough, the smaller village Vesper uses the city music instead of the Villages tune. This may have been an oversight by the programmers.
The song features a powerful melody with a lovely vibrato at the end of some of the measures. It also has percussion and a bass accompaniment. There is a brief moment when the melody cuts out and is given a higher pitch response from another instrument.
Cities is an unofficial name. It is track 6 in the NSF file.
