The piano is a precise instrument. Its pitches are arranged linearly without exception, and all notes possess a uniform envelope. Of course, there are differences based on pitch, but the mechanism for producing sound is almost entirely uniform. This instrument, which produces uniformly abstracted musical tones, has cultivated the human body as if confronting its own mechanism. Most instruments respond obediently to conscious human actions. For instance, the freedom of envelope in wind and string instruments allows for a wide range of expression in articulation. However, the piano demands a body that conforms to its mechanism. Perhaps the greatest distance between musical expression and the body is found in finger-played keyboard instruments, including the piano.

 The linearly arranged keys are well-suited to linearly arranged numerical sequences. Equidistant numerical sequences generate certain scales, and these scales can be assigned to the five fingers of the human hand. The compositional algorithm of this work involves developing notes outside of those assigned to the five fingers within that scale, through the "finger substitution" action unique to piano performance. If one understands this compositional algorithm, sheet music would be unnecessary. However, this is not particularly novel. This is because I feel that the piano itself visually represents the theoretical framework of music.
