Creating harmony or discord in metal sculptures involves a deliberate interplay of materials, forms, and textures. Harmony is often achieved through balanced compositions, smooth curves, and complementary finishes, evoking a sense of unity. For example, using polished stainless steel with rhythmic patterns can create visual cohesion. Conversely, discord is crafted through jagged edges, asymmetrical designs, and contrasting materials like rusted iron paired with sleek aluminum, provoking tension.

Techniques such as welding, forging, and patination further influence the emotional impact. Harmonious pieces may employ consistent patinas or symmetrical welding, while discordant works might mix rough welds with uneven oxidation. Lighting and placement also play roles—soft lighting enhances harmony, while harsh shadows amplify discord. Ultimately, the artist’s intent guides these choices, transforming cold metal into evocative art.
