The Fantasia and Fugue in G minor was composed immediately after the death of his wife, Maria Barbara, in 1720.
The great and wonderful drama of Fantasy, which evokes this event so painful, begins with a toccata episode, in which there is a game virtuoso not an end in itself, accompanied by dissonant chords that evoke the drama.
Follows a contrapuntal episode, which I think suggests resignation, but it is suddenly interrupted by a return to drama, marked by very innovative and dissonant harmonies, called "hardness et ligature".
Back then the issue of resignation, again followed by a progression that leads in the final episode extremely virtuosic and dramatic.
