>>50443495The 'snowiness' you're hearing comes from the compound meter, swung melodic rhythm, and highly directional melodic contours, all of which are common features of snow themes attempting to musically capture the concept of drifting snow—it just so happens that those techniques are also useful for representing falling ash. For me, however, the heavy horn lines and castanets lend the piece a weightier, more dour sound than what you'd typically hear in snow level music.
