Can you name the two scales that debussy used which help give his music a blurry sound.?

Debussy often used the whole tone scale and the pentatonic scale to create a sense of ambiguity and blur in his music. The whole tone scale, consisting of six consecutive whole steps, lacks a strong tonal center, while the pentatonic scale, with its five notes, offers a more open, less defined harmonic structure. Together, these scales contribute to the dreamy, impressionistic quality characteristic of Debussy's compositions.
