It is in E minor and is in binary form.

• A [a (bars 1-8) + b (bars 9-16)]
• B [c (bars 17-24) + a1 (bars 25-32)]

Contrary to the image evoked by its Japanese title, this piece in E minor possesses a somewhat serious atmosphere. The main motif is highly repetitive, moving back and forth, which also conveys a nuance of impatience or restlessness. The frequent pauses, as if to confirm something, in bars 5-6, 7-8, and 13-14, might be suggestive of something. Given the nature of the piece, the original meaning of its title might have been a caution against frivolousness or carelessness.
