Coloring-in Piano: Indiscrete Musical Elements are Essential for Performers

In this description, we propose a new musical instrument named the “CiP (Coloring-in Piano)” that can facilitate to externalize musical expression of performers. Conventional music consists of two kinds of elements, i.e., "discrete elements" and "indiscrete elements." Pitch of each note and basic rhythm of the notes (i.e., time value of each note) described in a score are the discrete elements, while tempo, "Artikulation," "Agogik," "Dynamik," and so on, are the indiscrete elements. CiP releases the performers from a non-creative task to operate one of the discrete elements, i.e., the pitch. As a result, CiP allows the performers to concentrate on creative task, that is, control of the indiscrete elements. Moreover, CiP allows the performer's simultaneous operation of all of the indiscrete elements. We provide three performance data to demonstrate effectiveness of CiP.
