[Instrumental] [Subject - solo organ, low register] [Answer - second voice enters at the fifth, subject continues] [Exposition - third and fourth voices enter, stretto building] [Episode - sequential chromatic descent, mounting tension] [Development - imitative entries accelerate, harmonic instability] [Stretto - all voices overlapping, exhilarating density] [Climax - full organ, fff, chromatic convergence] [Final cadence - Picardy third resolution, ominous stillness]
