A Musical Instrument Played With Water

The hydraulophone is a unique instrument that creates sound by physically blocking streams of water with your fingers. Unlike a flute or piano, the water itself acts as the vibrating medium to generate musical notes.

This invention works by manipulating pressurized liquid jets that resonate when touched. Because it relies on tactile feedback rather than just hearing, it has become a powerful tool for low-vision individuals to explore sensory music. It is truly a rare marriage of fluid dynamics and artistic expression. You are essentially playing a fountain as if it were a keyboard.
