I think I earned some extra points yesterday...

At the end of my organ demonstration at the church the students wanted to listen to different acoustical qualities while walking around the room. In some places you get to hear more high-pitched sounds, in others - low-pitched sounds and in some places - pedal pipes sound the most prominent etc. So I improvised this piece for them. After that my boss at the university came up to me and asked what was this piece? I said I improvised it. Her eyes opened wide in awe. I think I may have earned some extra points with her yesterday...
What do you think?
