The haunted house in c minor for Organ by beethovenbd

Hello,
This is a rather older piece of mine, composed on the 23th of october last year. I hadn't uploaded it yet since I was rather in doubt about it. But since several people told me they liked the song I decided to upload it at any rate.

It's a ciaconna in c minor, the bass is repeated a number of times above which an eery, against-the-meter melody is played.
The piece despite it's shortness is still in a-b-a form, the b part *however short* being in Eb major.
