No. I was actually going to write separate functions for each "filter".
Then I thought it would be nice to call them from this function. This
way code can easily be reused and if anyone wants to modify a passage by
doing things like getting then enharmonic spelling of flats to sharps or
whatever. I am not hard set on these ideas. I am just exploring it for
any advantages/disadvantages.
