# Suno Replace Section

> Regenerate a 6 to 60 second section of a Suno song with new lyrics and style tags, such as a weak verse or chorus, and keep the rest of the track intact.

The **Suno Replace Section** node regenerates one part of a Suno song, such as a weak verse, and keeps the rest of the track. You choose the time range, write the new lyrics or content, and add style tags. Suno then fits the new section into the song, so you do not have to generate the whole song again.

- Found in: Audio › Music
- Output: audio
- API type: `suno-replace-section`

## When to use it
- One verse or chorus is weak in an otherwise good song.
- You want to change the mood or the style of one section.
- You want new lyrics in one section and the rest unchanged.
- You want to try different bridges or transitions between sections.

## Quick start
### Add the node

Press Tab on the canvas, or open the node picker in the sidebar, and choose **Audio › Music › Suno Replace Section**.

### Connect the song

Connect a [Suno Create Music](https://nodaro.ai/docs/nodes/audio/suno-create-music) node to the **Audio** input. The **Task ID** and **Audio ID** come from that node when the workflow runs.

### Choose the section

Set **Start Time (seconds)** and **End Time (seconds)**, for example `45` and `75`. The section must be 6 to 60 seconds long.

### Write the replacement

Write the new lyrics or content in **Prompt**, and style tags in **Tags**, for example `pop, anthemic, female vocal`.

### Run it

Click **Run**. The song with the new section appears on the node.

Workflow: New chorus lyrics replace the part of the song between 45 and 75 seconds.

- Suno Create Music → Suno Replace Section (audio)
- Text → Suno Replace Section (prompt)

## Inputs
| Input | Accepts | What it does |
| --- | --- | --- |
| **Audio** | A Suno node, such as Suno Create Music | The song to edit. The node reads its Task ID and the Audio ID of the selected version. |
| **Prompt** | Text nodes and pickers | The new lyrics or content for the section. |

The output, **Audio**, is the song with the replaced section.

## Settings
| Setting | What it does |
| --- | --- |
| **Task ID** and **Audio ID** | The song to edit. Both are filled from the connected Suno node when the workflow runs, and a connection wins over typed values. Paste them only to edit a song from an earlier session. |
| **Start Time (seconds)** | Where the section starts, 0 or more. The default is 0. |
| **End Time (seconds)** | Where the section ends. The default is 30. See [Choose the section](#choose-the-section) for the limits. |
| **Prompt** | The new lyrics or content for the section, up to 5,000 characters. A longer text is shortened to fit. The prompt is required. |
| **Tags (optional)** | Style and genre tags for the new section, up to 500 characters. |
| **Title (optional)** | A title for the result, up to 80 characters. |
| **Full Lyrics (post-edit)** | The complete lyrics of the whole song after the replacement: the changed and the unchanged parts together. Suno uses them as the lyric sheet of the finished song. |
| **Negative Tags (optional)** | Styles to exclude from the new section, for example `rock`. Up to 500 characters. |
| **Pre & post text** | Text that is always added before and after the prompt. It is hidden from people who use your workflow as an app. See [Prompt pre and post text](https://nodaro.ai/docs/concepts/prompt-pre-post-text). |

## Choose the section

The replaced section is the time between **Start Time** and **End Time**.

- **Length.** The section must be between 6 and 60 seconds long.
- **Share of the song.** The section can be at most half of the song.
- **Position.** The section can sit anywhere in the track. From 100 to 130 seconds is a valid section.

Listen to the song carefully before you set the times, and note where the part you want to change begins and ends.

## Tips
- **Always fill in Tags.** Use at least basic genre tags. A descriptive prompt together with relevant tags gives the best replacement.
- **Give Suno the full lyrics.** With **Full Lyrics (post-edit)**, the new section fits the words of the whole song.
- **Work section by section.** Refine one part at a time instead of generating the whole song again. At 20 credits, a replacement costs less than a new song.
- **Try alternatives.** Replace the same section with different prompts to compare bridges or transitions.

## Frequently asked questions

### How long can the replaced section be?

Between 6 and 60 seconds, and at most half of the song. The section can sit anywhere in the track, for example from 100 to 130 seconds.

### Does the rest of the song change?

No. Suno regenerates only the time range you choose and keeps the rest of the track intact.

### How many credits does Suno Replace Section cost?

Each run costs 20 credits, which is less than generating the whole song again.

### Can I edit a song from an earlier session?

Yes. Copy the Task and Track IDs shown under the player of the Suno Create Music node, and paste them into Task ID and Audio ID.
