Load any mp3-file from your personal collection and start jamming on your keyboard to adapt the music visualization to your perception of the rhythm. The game does not restrict the keyboard input to specific keys, nor does it impose a pattern of beats. A Sense of Music is about your personal interpretation of the music.
The experience reaches its full potential after several plays. Discover the visualization, master the controls, and (most importantly) accept the lack of goals and judgment (easier for some than for others). It is only after these stages that you can experience this game as it’s intended: not as a goal-oriented game, but as an unrestrictive musical experience.
The experimental part of A Sense of Music is that it tries to challenge the boundaries of video games as a medium. Is it possible for a game to be fun without containing challenge or story? Would it still feel like a game?
