Because they were programmed to!
Okay, I know that I normally blog about heavier subjects, but please indulge me in a moment of whimsy.
Recently on my personal blog I did an entry featuring a bit of computer animation I had discovered that offers a fascinating presentation of Bach’s Toccata and Fugue in D Minor (it’s really cool).
But this was not the only animation in the series. There are a lot of them, and one that caught my eye was titled “Bach, Jesu, Joy of Man’s Desiring, from Cantata 147 (sung by alien robots).”
Alien robots singing a favorite like Bach’s “Jesu, Joy of Man’s Desiring”? That’s worth checking out.
BTW, here is what the alien robots are singing in German:
Jesus bleibet meine Freude,
meines Herzens Trost und Saft,
Jesus wehret allem Leide,
er ist meines Lebens Kraft,
meiner Augen Lust und Sonne,
meiner Seele Schatz und Wonne;
darum laß’ ich Jesum nicht
aus dem Herzen und Gesicht.
—from BWV 147, Chorale movement no. 10
The usual English translation of this does not correspond with the German text, but here is a more literal translation (source (see no. 10)):
Jesus shall remain my gladness,
Essence of my heart, its hope;
Jesus from all grief protecteth,
He is of my life its strength,
Of mine eyes the sun and pleasure,
Of my soul the joy and treasure;
Therefore I will Jesus not
From my heart and sight allow.
So with no further ado, alien robots sing “Jesu, Joy of Man’s Desiring”!
