The audio begins with a high-pitched, somewhat piercing hum, similar to the sound of a finger rubbing against the rim of a wine glass. The sound gradually intensifies, creating a wailing tone that might be considered painful to some listeners. The hum continues to oscillate, embodying the essence of a wine glass being stroked, and it is this repetitive motion that maintains the high-pitched, resonating hum. The sound ebbs and flows in its intensity, creating an almost hypnotic rhythm. It's a unique symphony of sound that encapsulates the essence of a wine glass's song.
