Who knew such a happy time could be in such a sad key?

"Deepest depression, lament over death and loss, groans of misery, ready to expire. Harrowing. Melancholic."

Arguably the saddest key, F minor sees limited use in both jazz and concert settings, typically being reserved for chorales or deeply sorrowful moments, though there are some notable pieces in the key, including most arrangements of "God Rest ye Merry, Gentlemen."
