Curves

Two frequencies. One phase. The figure they trace together is never the same twice — unless the mathematics says it must be. Harmony made visible.

Zone I — Origin & meaning

Sound drawn on a surface

In 1857, French physicist Jules Antoine Lissajous attached a mirror to a vibrating tuning fork and directed a light beam at it. As two tuning forks vibrated at different frequencies, the combined motion of light traced complex, beautiful curves that captured the mathematical relationship between two sound waves.

Frequency ratios determine the shape completely. A 1:1 ratio makes an ellipse. A 1:2 ratio makes a figure-eight. Given the frequencies and phase offset, there is only one possible figure — deterministic and total.

"The Lissajous figure is the portrait of a relationship between two oscillations. It shows not the waves themselves but how they listen to each other."

Lissajous figures appear in physics laboratories, oscilloscopes, and acoustics. The same figure that describes a major third interval in music also describes a specific geometric shape. Sound and form are the same mathematics.

Zone II — The mathematics

Three waves, three axes, one projected surface

The classic Lissajous equations describe a 2D figure from two sine waves. The Szumski Tradition Engine extends this into three dimensions: a third frequency on the Z axis, then a 3D rotation before the figure is projected flat. The same deterministic mathematics — but now the curve exists in space, and the viewing angle reveals hidden structure.

x(t) = sin(a·t + δ)
y(t) = sin(b·t)
z(t) = sin(c·t + ψ)
