Publication notes
What you are looking at.
Original contemporary illustrations, with their image type and purpose kept visible.
The cover composition

The asymmetrical ivory-and-bronze mask, surrounding surfaces and drum forms were generated for this project with OpenAI image generation. They are not photographs of physical objects. The mask is an invented contemporary design without a claimed cultural or historical provenance.
The design-study board

The six detail images are crops of one generated study board: sketch, silhouette, palette, ornament, material impressions and simulated lighting. Cropping and WebP conversion were used to prepare responsive editorial assets. The images are not evidence of a physical making process or material test.
The percussion still life

This original composition illustrates general instrument forms. No maker, collection, tradition or performance history is assigned to the depicted objects. An actual instrument’s sound cannot be established from this rendering.
