Debussy’s piece “Jimbo’s Lullaby” opens with a left hand melody based on a d minor pentatonic scale whose oriental mood and slow tempo meant to be played “deux et un peu gauche” evoke the image of a playful elephant. At measure ten the mood begins to shift, and at mm.19-20 the piece moves away from the d minor tonal center and seems to focus more on the pitches F and G; these polychords seem to suggest at a feeling of bitonality which is reinforced by the secundal harmonies that move from V-I (F and G move to C and D). By highlighting F and G as tonal hubs, the listener feels aurally removed from the d minor key so that when the opening melodic motive is weaved in again at measure 28 accompanied by the secundal harmonies of F and G, it is harder to recognize and more dissonant; almost sinister. Through the use of the whole tone scale (beginning at measure 41) the tonal center is further obscured. This dissonance, created by unusual harmonies, the whole tone scale, and an obscured tonal center, saturates the overall mood of the piece; turning what would be simple French lullaby melodic motives into more interesting and eerie sounds.
