Buna Tetu Posters

Buna Tetu Posters is a generative poster design series created for Jazz Café Buna Tetu, translating the sound of jazz into visuals through code-driven design. Each poster is born from the data of a specific track, creating a direct dialogue between music and image.

The visual language draws inspiration from the iconic jazz posters and record covers of past decades, where bold, structured typography met fluid, rhythmic forms. The compositions are generated in Processing (Java), using sound analysis and frequency visualisation techniques to create dynamic, responsive graphics. Different frequency bands—bass, mids and highs—activate and shape the visual elements, pulsing in sync with the music.

Every track results in a distinct visual composition, where sound dictates the distribution of shapes, the rendering of colour and the intensity of the piece. Just as no two jazz performances are ever the same, each poster in this series is unique, capturing the energy of a fleeting moment.

The outcome is a collection of abstract, rhythmic posters that channel the energy, texture and improvisational spirit of jazz, reinterpreted through the lens of digital and algorithmic design.igital, algorithmic design.
