The final of the four short fantasias de guitarra. Like the others, it is short, 58 compases, tiempo C = despacio. The work begins with imitative statements (non-canonic) of theme 1, until bar 13, then proceeds freely. The sombre mood is largely through the semitone of consistent Bb, throughout, and realized in a predominantly homophonic texture. Bars 20-22 have a little sequence of descend 3rds. The rest of the work is free.
