We make sense of repetition: repeated patterns (a.k.a. culture), repeated actions (a.k.a. performance), repeated words (a.k.a. folk narrative), repeated rhythms and melodies (a.k.a. folk music), repeated forms and dispositions (a.k.a. material culture; indeed re is the ablative case of the Latin res for thing or matter). Our fields were formed and reformed around various notions of return: the ways in which people (in various times and places) recycle ideas, restore behaviors, remix words, recreate tunes, reuse objects, remember customs, remake, repair, rehash, refine and reduce. This is our special remit within the humanities and social sciences.
