Andrea Bocelli | Because We Believe

Bocelli’s “Because We Belive” has a textbook example of a “common tone” modulation: a single note is sustained through key change, thus transforming its harmonic function. And the second, at 4:20, is the rare downward modulation, moving from E to D. David Foster is at the keys (he co-wrote the song with his daughter Amy for the 2006 Turin Olympics).
