Ce qu'a vu le vent d'ouest

Ce qu'a vu le vent d'ouest (What the West wind saw) is the 7th piece in Claude Debussy's first set of preludes. This piece is supposed to evoke the destructive power of the wind as opposed to Le vent dans la plaine, which only evokes bursts of wind. This piece is unrestrained in virtuosity. It can become extremely loud and technically demanding.

The piece is also extremely heavy in tritones, which can be found in all of the booming chords and arpeggios. It is also heavy on whole-tone motifs.
