“Delphi’s Dancers” refers to a Greek sculpture favored by Debussy, depicting three priestesses of Bacchus (Dionysus). The first part (measures 1-10) consists of two sections, each five measures long. The first episode comprises five measures: two slow, sarabande-like measures with an accent on the second beat, followed by three measures consisting of a dotted melody and parallel chords. The second episode is a recapitulation of the first episode, presented at an octave higher pitch and showing development. The second part (measures 11-24) is structured as a progression of four episodes:

• The first episode (measures 11-14) features a dotted melody and parallel chords moving over a sustained tonic bass.
• The second episode (measures 15-17) highlights a dotted melody in the inner voices.
• The third episode (measures 18-20) sees an increase in tranquility, moving towards ppp.
• The fourth episode (measures 21-24) is transitional.

The third part (measures 25-31) serves as a coda, recalling the beginning of the piece and bringing it to a close.
