The 9 genres where BPM doesn't apply — and what to write instead

Description and use

AI music generators require a BPM, which destroys free‑time genres. Replacing zero values with null and adding "no rhythm" to prompts allows correct generation and lyric writing following a five‑stage arc.

Problem

AI music generators force a tempo value, which destroys free‑time genres that have no pulse.

Outcome

Free‑time genres are correctly represented without a BPM, leading to accurate AI generation and clearer songwriting guidance.

Workflow

• Identify free‑time genres in the catalogue.
• Replace BPM 0 with null/empty in CSV/JSON.
• Update AI prompt to include "no rhythm" or "indeterminate timing" instead of a tempo number.
• Adjust style influence to ~91 and weirdness >70 to maintain structure.
• Write lyrics in breath‑lengths, not syllable counts, following the five‑stage arc (emergence, accumulation, peak, resolution, ending).

Evidence

Until recently these nine were stored in my own dataset as BPM 0

They are now an empty cell in the CSV, null in the JSON and a dash in the Markdown table
