Theory of the correspondence of music and image

Transfer of Music into a Graphic Image

Starting Point

Music is developing in time, while image is developing in space. However, both music and image have beginning and end. In the music these are obvious, but some explanations are required when it comes to images: the beginning here is the spot our eyes see first, and the ending is the point when we stop viewing the image. Thus, to capture the image human glance moves in space and creates a path. If we set a common point from which the majority of people start examining the image, we will be able to correlate it with the beginning of music.

 

Correspondence of Formats

Human consciousness strives for orderliness, and for this reason we often make judgments using pairs and contrasts: east-west, south-north. Such concepts as forward, back, right, left also originate from the human nature, and describe the easiest way of orientation in space. That is why images are usually placed into a rectangle having four sides.

 

 

The angles of rectangle allow finding the center faster and dividing the rectangle into proportionally equal parts.

 

Speaking of our striving for orderliness, we can also mention poetry with its rhyming of line into a pair or by alternation. In the music this function is performed by the standard four-bar rhythm and four-bar melody composition. Even if melody does not end within the limits of four bars, this number is anyway often divisible by four (for example, eight or twelve bars).

 

Arrangement of Music on the Plane

Diagonal corresponds to the beginning of music bar, because it helps the human eye to orientate when examining the image. Therefore, the first note will be laid down on the diagonal. Diagonal, vertical and horizontal intersections through the center of rectangle correspond to the strong beats of the bar and "time" coordinate. Distance from the center to the edge of rectangle is the second coordinate that reflects the pitch of note.

 

 

The rectangle should be isosceles (square), as the bars are equal by time. Distance from the center to the edge corresponds to octave; lower notes are located closer to the center, while high notes are closer to the edge of square.

 

The notes are transferred to the plane to their respective paths. There are 12 paths for the octave, according to the number of semitones in the octave.

 

 

In this fragment of diagram the motion begins counter clockwise from the upper right diagonal. This example demonstrates the sounds of very low octave note "Do" would be barely audible. Accordingly, the functional diagram also has in its center an empty square representing the very low octave, which is "not audible".
