Here's where you can find a midi for The Last Words of Copernicus. (indexes under The) I think the midi's here were created from the notation in the Sacred Harp by someone trying to learn the tunes on his own. It's meant to be used with the notation. The last 4 lines are a fuge with some repeating phrases & then all repeated. Have fun.

Words are by Philip Doddridge, 1755, music by Sarah Lancaser, 1869. She wrote 3 good tunes that are used in the Sacred Harp.

There's nothing quite like the alto's blasting their line on "And thou refulgent orb of day." An image strange to our ears, but nothing funny sounding at all about it, just wonderful.
