* A group of people chanting: This could be a religious ceremony, a political protest, or even a group of friends celebrating. The wind amplifies their voices, making the chanting sound even more intense and resonant.
* The wind itself: The wind rustling through trees or across open land could be interpreted as a chanting sound, especially if it's a strong wind with a mournful quality.
* Nature's sounds: The wind could be whipping through leaves, creating a swooshing, almost rhythmic sound, that resembles chanting.
The specific context of the words would help determine the exact meaning. For example, if the phrase is used in a story about a spooky forest, the chanting could be associated with supernatural forces. If it's part of a poem about a political rally, it would describe the passionate voices of protesters.
