The Tongue Music system is an experimental instrument using the tongue, rather than the hand, to generate sounds. There is one person performing in front of projector, which displays an abstract video image consisting of hundreds of dots. The performer controls the mouse with his tongue to simultaneously manipulate the video images (the color and size of dots are changed along with music), the piano sound, as well as the presence or absence of a beat.
