Holy God Damn

that Daniel Ingram is one sneaky son of a mare. He actually worked a musical pun into one of the four numbers he did for the Canterlot Wedding double episode.

There was actually a double meaning in the song. The song is in the key of Db Major (just like winter wrap up!) . That means that the root chord is a Db major chord. Usually, a Ab major chord will lead into a Db major. This is the V-I chord progression and it is also known as the Authentic Cadence (stick with me here). Now, it seems to resolve to a sadder chord at the end of the phrase. Instead of ending on Db major around 1:16, it lands on Bb minor: the relative minor of Db major. Now, when a chord progression seems to be heading to the root chord but lands on the relative minor instead, that is called a... Deceptive Cadence

Also worth noting, listen to how Twilight sings the last "forever" in the song. Her little cadenza (I am seriously not making these words up) quotes the opening notes of the theme song
