Long abstract:

In daily culture traditions tend to change along with cultural and moral changes in the surrounding world. However, some traditions are less variable than others. For instance the giving of family names in certain cultures tends to remain a stable tradition, whereas there is much more variability in the modern retelling of traditional folktales, at least in the western world. Other traditions, like the singing of folk songs or amateur theater may become part of the local canon - some elements may remain stable, while other elements change or disappear over time.
