Theory of the correspondence of music and 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".
