Counterpoint in Composition 1.
Vertical/Horizontal and Tonal Logic
Greyscale The scale I use, seen as percentages of black, is 0%,25%,50%,75%,100%. The Contrapuctus 3D piece seen at the top of this page, was actually the first composition I created using this 5 tone scale. All previous motifs were defined using only black, white and a mid grey (50% black). I actually produced some of my most distinct motifs using just 3 or 2 tones. Many of the later works on this site use both a 7tone scale and a full (8-bit) 256 greyscale, although this number has little significance as it is simply the means by which I render a full black to white graduation. The tone chart, above right is a scale I designed to assess values for printed output. The printing technology I now use, however, is so well calibrated that the ideal values described above left produce perfect printed results.
Tonal Symmetry Logic One key device I have evolved in my work is something I call tonal symmetry. A simple demonstration of this can be seen in the logic diagram above. In essence it is a simple tonal counterpoint exercise where horizontal elements @ (25% grey) is balanced by vertical elements @ (75% grey). This provides an interlocked grid structure onto which the composition is set. The real invention comes at the point where vertical and horizontal intersect. The simplest solution to this might be something like that seen below left, but that would be plane dull.
The rotating squares in the animation below, indicate how the Square root of 2:1 proportion* meters the growth of this simple motif.
*In a square of sides = 1, the distance between opposite corners = root2.
Counterpoint in Composition 2.
Directional Emphasis

Compositional Movement Directional force and movement within a visual composition is produced by all shapes to some degree or another. Essentially, ordered variety of form will create movement around a composition as the eye will naturally move from areas of activity to areas of inactivity and vice versa. All the motifs from 3 through to 10 have a diagonal directional emphasis, but achieve it in varying ways. Compositions No.1 and No.2 contrast strong diagonal forces with a non-directional, centrally focus motifs. No.5 is an invention on a theme of symmetric form and tone which creates a diagonal passage through the composition without using any significant linear components. The ‘type’ of symmetry here is a conceptual symmetry of themes and parts as opposed to a literal axial symmetry like that created by a mirror and seen in No.10. This thematic symmetry, however, in this motif does operate about an central x and y axis. We might think a simple bold arrow or bold stripes might produce the strongest directional movement, but I believe there are much stronger compositional solutions at hand with the use of a little invention. Take a look at No.4. We see two points of focus at the ends of the arrows, but this intensity is quickly lost as we move into the composition leaving dead areas. The square composition is cut in half by the arrow and there is no essential and continuous unity between the negative spaces around the arrow. A simple jarring and discordant arrangement like that in No.4 may well be desirable if this is the expression that is sought. Compare No.4 with the continuous and evolving movement in No.6. This is one of my favourite motifs and I have pretty much exhausted its use over the years. Its geometry is very pure and it creates a flowing varied movement with very little fuss. No.9 is quite amorphous by comparison to the rest of the motifs, but still, nonetheless creates some varied forces. No.11 and No.12 create a rotational movement with no diagonal emphasis. As I have discussed previously on this site, very rarely do I utilise linear stripes in my work like those shown in No.8. This is partly due to the somewhat arbitrary nature of the geometry needed to define them, but more simply, it is to do with their intrinsic lack of progressive variety. One way I have gotten round both of these ‘problems’ can be seen represented in No.7. The type of visual dynamic however creates another problem of its own. This is the ‘Op Art’ phenomenon, which whilst providing an instant effect, for me has more to do with sensation and illusion, than order and beauty. Both No.7 and No.8 are still, however examples of emphasised directional movement within a visual composition.
