Abstract
Since many years ago, musicians have composed music based on the images that they have had in their minds. On the other hand, music affects people’s imagination while hearing it. This research provides a method that can transform shape to music and music to shape. This method defines musical notations for horizontal, diagonal and vertical line segments, filled circle and curve with different colors, which are the basis of many shapes in transforming shapes into music. Then these primary mappings are generalized to more complex forms to transform any shape. Moreover, music can be transformed into shape by this method. For this transformation, primary musical notations such as simple notes, notes joined by a legato, notes with a staccato, notes joined by a legato and have crescendo or decrescendo and notes with an accent or a trill are defined. These primary musical notations are generalized to more complex forms to transform any music into shape. Also, the method of this research can be used in music cryptography. It employs mapping of notes in a twelve-tone equal musical system into shapes and mappings of shapes with an equal line width and different colors into music. Keywords Musical notation . Synesthesia . Music cryptography . Graphical notation . Composition

1 Introduction Music is an art form that has been a fundamental constituent of human life and has developed enormously through millenniums. People have made music to express their emotions and listened to it for many reasons such as empathy and joy. Their reactions to music have always been an interesting subject. Music listeners have different listening styles, such as compensating (changing the mood), concentrated (like to close eyes), emotional (paying attention to what types of feelings are expressed through the music) and associative (having pictural images) based on previous researches. In the associative type, they experience musical imagination that is an action made by the minds [11]. Moreover, some people see colors, shapes and movements as a result of hearing musical tones. They are synesthetic meaning that they experience a cross-sensory interaction in perception [41]. An example of these people is the seventeenthcentury physicist Isaac Newton, who identified seven discrete light entities that matched the seven discrete notes of an octave [6]. A
