The Golden Rooster

Question. Can a single creator build and validate a commercially viable music venture from one original fictional universe?

Thesis. A coherent fictional world can carry several connected music products and audience experiences, and each new product built on it costs less to make and finds listeners more easily than a stand-alone release would.

What we are doing. The world is De Wereld van de Gulden Haan: a fictional lordship in the Burgundian Low Countries around 1450, with a lord (Diederik van Cok), his house (Huis Cok) and a rival. From it came a fictional travelling troubadour, Maerten Veelspraeck, who is the recording identity. His catalogue: a 13-song Dutch-language narrative album, Waar de Haan Waakt, and a six-track instrumental dance EP, Tot de Haan Kraait, planned for 18 December 2026. Around the music: cover art, short video concepts and a design for a live "court" at medieval events. One creative director; AI-assisted production.

How we will judge it.

• Production leverage: hours and iterations per approved track or asset go down for later products [THRESHOLD].
• Retention: saves, repeat listeners and follows per release [THRESHOLD].
• Crossover: the share of EP listeners who go on to the album [THRESHOLD], and listening outside the Dutch-speaking market, starting with Germany [THRESHOLD].
• Live: participation in a small pilot, and the share of participants who go on to the music [THRESHOLD].
• Economics: revenue minus variable and marketing costs, with founder hours recorded separately.

What would make us stop. If neither release earns meaningful repeat listening after a fair test [THRESHOLD], development pauses until we have a new hypothesis. If the world adds nothing measurable beyond the music alone, we simplify it.

Reports R01–R08 were written retrospectively in October 2026 from project notes. Later reports are written as they happen.
