Well, to me, if slow music in minor keys would be depressing, I would be dead for deacades already.
About the opening chorus of the SMP: I find it beautiful and very moving, but not depressing at all. The closing lines
Sehet ihn aus Lieb und Huld / Holz zum Kreuze selber tragen and
Erbarm dich unser, o Jesu are expressions of forgiveness and consolation for me. It grabs me in an invigorating way. After listening to it, I want to hear it again.
I've seen cantatas like BWV 56 and 82 often desribed as sad and depressing. Again, I find them uplifting. "Ich will den Kreuzstab gerne tragen..." I would
like to bear the crossbar with
pleasure. Nothing sad about that IMO. BWV 82: about the song of Simeon, who asked God to die because he has never been so happy. "Ich freue mich auf meinen Tod." A bit odd maybe for many modern ears in modern times (I'm not a faithful Christian myself, either), but Bach's music is so convincing to me that I can almost naturally identify with it.
Well, the list could be endless. And not just for Bach. Maybe I would do best to conclude that I do not know of any depressing music, except music that I dislike very much.
