#521: O Day of Rest and Gladness

Who is the composer?

Christopher Wordsworth, nephew of William.

Is the song really addressed in praise of the day of the week?

Yes.

What is the "silver trumpet"?

Not sure. Unless it's like representing organs or some kind of church music, but that would be a weird phrasing.

Is the alto part pretty boring?

Let's just say there are a whole lot of E's repeated, especially in that third line.
