Alba is a beautiful and poetic word for "dawn". While you might know the more common word amanecer, alba carries a more literary and romantic feeling, making it perfect for songs.
In this powerful ballad, Andrea Bocelli sings, "Que eres como el alba que yo espero" (You are like the dawn that I wait for). He uses this lovely metaphor to express that his beloved is a symbol of hope and new beginnings, bringing light to his world just as the sun rises to end the night.
This is a song about a love so powerful it feels like it comes from another world. The Italian tenor Andrea Bocelli sings about someone who is his "tesoro" [treasure] and the "alba" [dawn] that he waits for. Their presence is everything. When they are near, "La noche se despide ya" [The night says goodbye now], as if their light is enough to chase away all darkness.
There's a constant connection to the sky, or heaven. The singer says that if his love is dancing in the sky, "Al cielo me escaparé" [I will escape to the sky] to be with them. This love is so huge it creates its own heaven on earth, a place to love "Hasta el final" [Until the end]. The song ends with an incredible statement of devotion: the person he sings to is so important that they are the one who "mueves el mundo" [moves the world] and makes the wind blow.
