Why does Suno rewrite a Style prompt and add elements such as a male-female duet?

AI prompt: Is Suno supposed to change the text entered in the Style field? Answer: Yes, in Suno v6 the Variety slider is designed to adjust and update style prompts. That explains why a prompt specifying a male rock vocal can be rewritten to include a male-female duet: the displayed rewrite is part of the enabled variation behavior, not proof that the original prompt exceeded the character limit.

AI prompt: How can a creator stop Suno from rewriting Style tags? Answer: Set the v6 Variety slider to 0 before generating. Suno’s official v6 FAQ says this retains full control of style tags, matching Reddit respondent u/sighbots’ practical answer; higher Variety settings deliberately allow more prompt variation.

AI prompt: What is the best troubleshooting workflow when Suno still changes the intended vocal or arrangement? Answer: Save the original prompt, set Variety to 0, make the desired vocalist and exclusions explicit, and test one change at a time across paired generations. This controls prompt rewriting, but generative output remains probabilistic, so “male vocal” can guide the model without guaranteeing an identical performance on every render.

Reddit source: “I have a question about Style Prompts.” Posted October 7, 2026 by u/TauRyan. Named respondent u/sighbots answered that Variety rearranges the prompt and that 0% leaves it unchanged; Suno’s official documentation independently confirms the core setting behavior.
