I played along with this on a little Yamaha keyboard. I'm assuming this is C Minor. 2 main chords I managed to identify were F Minor and Eb Major. I think it's classical in that you've recreated classical instruments such as the Harp and Glockenspiel. (If i'm correct?) The motif itself is like something you'd find from the happy techno genre. A bit like DJ Satomi. You've added strings but they sound like bare fifths or simply octaved. I'm not sure, but then again i am tone deaf. I would have loved more harmonical experimenting instead of using your average major and minor chords. The motif itself is not bad at all, very promising infact, if you did more with it. Overall, it was alright - not terrible at all. Good stuff mate.
