Lyrics: Cecil Frances Alexander, 1848.
Music: Several tunes have been put to Mrs. Alexander’s poem, including ROYAL OAK by Martin Shaw, BRIGHT AND BEAUTIFUL by WIlliam H Monk, and GERALD by Ludwig Spohr.
I can’t embed, but you can listen to a boy’s choir from South London called Libera singing composer John Rutter’s tune for this hymn. Absolutely beautiful. I remember my older children singing this tune when they were in a homeschool choir called Joyful Sound. I liked it then, and I like it now.
Theme: And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day. Genesis 1:31

1. All things bright and beautiful,
All creatures great and small,
All things wise and wonderful,
The Lord God made them all.

2. Each little flower that opens,
Each little bird that sings,
He made their glowing colours,
He made their tiny wings.

3. The rich man in his castle,
The poor man at his gate,
God made them, high or lowly,
And order’d their estate.

4. The purple headed mountain,
The river running by,
The sunset and the morning,
That brightens up the sky.

5. The cold wind in the winter,
The pleasant summer sun,
The ripe fruits in the garden,−
He made them every one.

6. The tall trees in the greenwood,
The meadows where we play,
The rushes by the water,
We gather every day.

7. He gave us eyes to see them,
And lips that we might tell,
How great is God Almighty,
Who has made all things well.

“I believe in God, the Father Almighty, Maker of heaven and earth.”
Mrs. Alexander wrote this hymn and thirteen others to help children in her Sunday School classes understand the meaning of the Apostle’s Creed. All Things Bright and Beautiful was meant to illustrate that first line of the creed.

There’s some controversy about verse 3 with its rich man/poor man contrast and the idea that God ordains all things, including an individual’s wealth or poverty. I don’t have any problem with that bit of theology (see I Samuel 2:7, James 4:10, and many others), but some do. Z-baby recently memorized this poem (without verse 3), but she heard me playing the song by Libera, and she was surprised that her poem was a song.
