Lyrics example

plaintext
[intro]
Piano keys fall gently, the evening breeze is cool.
That summer, heartbeats quietly grew warm.

[verse]
By the classroom window, sunlight slants across your face.
Borrowing half an eraser, fingertips spark like electric traces.
On the way home from school, bicycle bells chase the clouds.
You said the future is far away, but I wanted to walk to the very end.

[chorus]
Youth is an unopened letter, filled with brave vows.
Even if the world flickers bright and dark, with you I see the light.
Love is like early summer rain, sweet even when it soaks the dream.
We run toward tomorrow with laughter, hand in hand, never looking back.

[bridge]
Later, wind and rain tore apart the paper umbrella, silence replaced the answers.
But the song in my heart is still unfinished, waiting for one last "don't drift apart."

[chorus]
Youth is an unopened letter, filled with brave vows.
Even if the world flickers bright and dark, with you I see the light.
Love is like early summer rain, sweet even when it soaks the dream.
We run toward tomorrow with laughter, hand in hand, never looking back.

[outro]
The piano fades into the distance, starlight paves the long street.
The story is not over, the next page is still ablaze.

Content requirements

  • Originality: Don't copy published song lyrics or imitate the rhyme schemes and signature phrasing of well-known songs.

  • Content safety: Lyrics must not contain political, violent, pornographic, vulgar, horrific, or drug-related content. Keep the content wholesome and emotionally authentic.

  • Language: Only Chinese and English are supported.

Best practices

Write effective prompts

Describe the mood, scene, and instrument preferences in detail. The more specific the prompt, the closer the output matches your intent.

  • Recommended: Melancholic piano, rainy night yearning

  • Not recommended: Melancholic music (too vague)

Prompt examples for different styles:

FAQ

What's the difference between lyrics and prompt?

The lyrics parameter accepts your own lyrics. The model strictly follows these lyrics to compose and perform the song. The prompt parameter accepts a natural-language description of the desired music style and scene. The model then writes the lyrics and generates the music automatically. At least one parameter is required. If both are provided, only lyrics takes effect.

When should I use streaming vs. non-streaming mode?

Use non-streaming mode when you need only the final audio file — no incremental data is returned. Use streaming mode when you need to receive audio data incrementally during generation, for example, to play the audio while it's still being generated.

How long are the audio download URLs valid?

Audio download URLs expire after 24 hours. Download the file within this period. After the URL expires, call the API again to generate a new URL.

What are the parameter limits for streaming vs. non-streaming mode?

The character limits for lyrics and prompt differ between the two modes. In non-streaming mode, lyrics supports 5 to 350 Chinese characters or 5 to 2,000 English characters, and prompt supports 1 to 2,000 characters. In streaming mode, lyrics supports 300 to 350 Chinese characters or 200 to 250 English words, and prompt supports 5 to 1,000 Chinese characters or English words.
