Claude Debussy ： 12 Etudes No.3 “Pour les quartes” L.136

Centered on the interval of the fourth, this étude explores an open, incisive sonority and subtle changes of color. Overlapping tones and shifting chords unfold in brief groupings, while repeated material gains delicate differences in expression. Rather than projecting a single melody, the piece invites the listener to follow the movement of each voice and the resonance that lingers between sounds. In performance, the outline of the fourths should remain clear without making the tone harsh, and the pedal should be used carefully to avoid clouding the sonority. Carefully shaped dynamics and pauses bring out its quiet tension and transparent colors.
