Psalms are religious songs. A remarkable example of the motif in the fairy tales and stories of Hans Christian Andersen is At the Uttermost Parts of the Sea. The title is a quote from psalm 139 of the bible's book of Psalms, a psalm by David.
(...) yes, there was beauty indeed. The air was so fresh and soft; the moon shone so clearly; the trees and flowers were so fragrant; and the bird sat in such comfort, with feathers clean and dainty. How all creation spoke of love and beauty! The bird wanted to sing out the thoughts that filled its breast, but it could not; gladly would it have sung like the nightingale or the cuckoo in the springtime. Our Lord, who hears the voiceless hymn of praise even from a worm, understood the psalm of thanksgiving that swelled in the heart of the bird, as the psalm echoed in the heart of David before it took shape in words.
For weeks these mute feelings of gratitude increased. Someday surely they would find a voice, perhaps with the first stroke of the wing performing some good deed. Could not this happen?
Now came the feast of holy Christmas. Close by the wall a farmer set up a pole and tied an unthreshed bundle of oats on it, that the fowls of the air might also have a merry Christmas, and a joyous meal in this, the day of our Saviour.
Brightly the sun rose that Christmas morning and shone down upon the oats and all the chirping birds that gathered around the pole. Then from the wall there came a faint "tweet, tweet." The swelling thoughts had at last found a voice, and the tiny sound was a whole song of joy as the bird flew forth from its hiding place; in the realm of heaven they well knew who this bird was.
