1. Emphasis on things such as elegance and balance, some would say courtesy as well
2. Musical stress on harmony and mood, as well as a plethora of other adjectives.
3. Sudden interest in classical style and literacy. The western classical era focused on Greek and Roman heritage and key points, for example.
