Like music being played, like the sound of leaves blown by the wind.
The music played: The rustling sound made by stepping on the leaves is like the rustling music played with a sand hammer, which is very beautiful.
It sounds like the wind blowing the leaves: The sound of stepping on the leaves is also like the sound of the wind blowing the leaves. When the wind blows the leaves, the leaves rub against each other and make a rustling sound.
