Measures 21 to 34

In measures 21 to 34, the development begins.

Measures 21 to 27:

• The key signature disappears.
• A series of chords in quarter notes present a melody underneath the motif of the sextuplet.
• In the passages marked in blue, Debussy uses the hexatonic or whole-tone scale.

Measures 28 to 34:

• The G flat major key signature reappears.
• The sextuplet motif moves to the bass.
• The chords go to the upper voice.
• The chords are G-flat major and D-flat major (I and V degrees of G-flat major) separated by B-flat dominant ninth (III degree of G-flat minor).
• In measure 34, the motif of the sextuplet reappears in its original form, this time on G#.
