Small tune inspired by William Blake's poem. I made it for my English class

Here's the poem:

Piping down the valleys wild

Piping songs of pleasant glee

On a cloud I saw a child.

And he laughing said to me.

Pipe a song about a Lamb;

So I piped with merry chear,

Piper pipe that song again—

So I piped, he wept to hear.

Drop thy pipe thy happy pipe

Sing thy songs of happy chear,

So I sung the same again

While he wept with joy to hear

Piper sit thee down and write

In a book that all may read—

So he vanish'd from my sight.

And I pluck'd a hollow reed.

And I made a rural pen,

And I stain'd the water clear,

And I wrote my happy songs

Every child may joy to hear
