prologue, epilogue tags

[steltz]

We have prelude and postlude, but there are pieces entitled prologue or epilogue, and no such tags. Are they interchangeable enough to use the prelude and postlude tag? Otherwise they have to go under the generic "pieces".

[Davydov]

Neither are recognised on the MLA list, so "pieces" would be appropriate. We can review the contents of the "Pieces" category once all the tagging is finished -- assuming we're not all too old by then
