"Key Card Song" (just for fun!)

We recently took a family beak away from home. We stayed at "Jetty Hostel" in Hua Hin (Thailand) for 2 weeks. Jetty Hostel has key cards instead of traditional door keys. Each time we opened our room the lock played 3 notes, C-D-E up then E-D-C down again when the door was closed. Emilie challenged me to make a piano piece out of just these 3 notes when we got back home to Bangkok. Emilie said I could change the rhythm if I wanted to. I accepted the challenge. This video is my improvised 3 note "Key Card Song" -- it s not serious - it s just for fun.
