A hydraulophone is a tonal acoustic musical instrument played by direct physical contact with water (sometimes other fluids) where sound is generated or affected hydraulically.[1][2][3][4][5] The hydraulophone was described and named by Steve Mann in 2005, and patented in 2011.[6] Typically, sound is produced by the same hydraulic fluid in contact with the player's fingers.[7] It has been used as a sensory exploration device for low-vision individuals.[8]
