This is copyright free music for solo piano with a lovely light accompaniment and rolling phrases. The second half of the song takes on a slightly calmer tone.
The song is cute and has a classical feel with a bit of a looser atmosphere.
I think the song has an image of a kakuzatou rolling along on its journey.
It is recommended for background music for YouTube talk scenes and live-streaming. Besides, it would also fit for scenes of cooking/cooking, babies/children, small animals/pets, etc.
