1. Record cache set/fetch time.

Fog::Cache.write_metadata({:last_refreshed => Time.now})

2. Create some custom expirey method

      EXPIRE_TIME = (60 * 60 * 24) # day old cache.

I VI II V progression

Assuming you can 

1) Substitute the minor IV for a dominant IV and the minor II for a dominant II
2) Substitue any of the VI/II's (because of #1) or V for a tritone equivalent

So...Some notation/glossary for the below:
