Madrigal sobre un tema popular (El cant dels ocells)         Xavier Montsalvatge    (1912-2002)

When they saw the rising glow of God’s great star,
Which floods the earth abright;,
The birds arise in song, warbling all night long,
of joy and glad tidings.

Come, birds, come, and rejoice in the dawn,
And with the great lady;

Magpie, thrush and jay say “May is here”;
The goldfinch answers: “Every tree revives,

Every plant abloom as if it were spring.”
