In this audio, the unique technique of producing sound by blowing into a bottle is demonstrated. The initial sounds are akin to a soft whistle, created by gently blowing across the top of the bottle. As the intensity of the blowing increases, the sound deepens and resonates, reminiscent of a train's horn echoing in the distance. The rhythm and pace of the blowing vary, creating a range of sounds that oscillate between a light honk and a powerful, full-bodied horn. The bottle serves as a unique instrument, transforming a simple breath into a symphony of sounds, from soft whistles to resonating horns.
