Like parting mist in the form of curtains unfolding, the curtains reminiscent of suspended water drops in an iridescent crystal lattice. Or like candles with glowing halos faintly visible just outside a cave, their smoke snaking out and scattered by a breeze.
I gave a name to that particular texture: "the wind-blown wafting effect", like a ribbon tossed into the air and then descends undulating. It also appears in the opening theme of Prokofiev's Flute Sonata in D Major, op. 94, first movement.
