We learn how to play 'Wish It Could Be Christmas Everyday' by Wizard. Again, fairly basic open chords for this one, but it is fast. This song also changes 'key' from D to E.
A key is a family of chords, usually derived from the first chord in the song. The verses in this song are in the key of D (chords include D, G, A, Bm and Em). The chorus is in the key of E (chords include E, A, B and F#m). Notice that these chords are totally different with few chords in both keys. The best example other than this song is the end of a Westlife song, as they would sit down for most of the song, and then stand up at the key change!
