Hello Mark,

An arpeggio with a celesta-like tone gives this song a distinctive flavor.
Reminiscent of Mary Poppins and Harry Potter stories somewhere.
I think that it is also influenced by the key being minor.
I think Vocaloid has been used successfully in this tune.
The same melody was repeated many times, so it was a little monotonous as a whole, but it was a very fun song.
Enjoyed my listen lot.

Best regards.
