Can anybody help me to understand what the author means by the sentence in the bold text?
"There is crucifixion on those unisons of the Sonata in F-minor, the Appassionata. Even our God we make cry out with despair and fear on the cross in the night. Now he struggles, the muscles bunching as he tears convulsively from the squad nails in his flesh, the head droops and jerks back with flashes of agony. The draught of vinegar and gall ... Stumbling but furious I played, blundering terrible onward as agony does. The brooding of D-flat major de profundis. Presto!"
Leonard Cline, Dark Chamber, 1927
