Struck up - Tradução em português

´The trumpets sounded and the music struck up, and the dance commenced; but if Cinderella's beauty, elegant figure, and the splendor of her dress, had before drawn the attention of the whole room, the astonishment at her dancing was still greater. / Gracefulness seemed to play in all her motions; the airy lightness with which she floated along--as buoyant as thistle-down--drew forth a general murmur of admiration.´
