introductory motif in that the motivic change
from the sixth to the seventh is included as an ornament in the melodic line
(the G-flat).
Thus both the first and second subjects are derivatives of the introductory
motif. Réti emphasises the significance of this discovery, saying that these
lines of Chopin, "...so often described as the archetype of purely emotional
outpouring, are firmly rooted in structural ground."
Example 12: The
relationship between the first and second subjects of the first
movement
Example 13: Ornamented
version of the second subject (bars 57-59)
The third subject (beginning in bar 81) can be seen as a
combination of the first and second subjects, as shown in Example 14. The
brackets show the affinity between the second and third subjects, while the
beginning of the third recalls that of the first.
