# YuE2GenerateABC - ComfyUI Built-in Node Documentation

> This node generates ABC notation for a song based on a style description and lyrics, using a YuE2 text-and-lyrics model.

This node generates ABC notation for a song based on a style description and lyrics, using a YuE2 text-and-lyrics model. The resulting `abc` output can be connected to the YuE2 Generate Music node to produce audio.

## Inputs

| Parameter            | Description                                                                                                                | Data Type | Required | Range                     |
| -------------------- | -------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------- |
| `clip`               | The YuE2 model used to tokenize the style and lyrics and generate the ABC notation.                                        | CLIP      | Yes      | -                         |
| `style`              | Text describing the musical style of the song. Supports multiline input and dynamic prompts.                               | STRING    | Yes      | -                         |
| `lyrics`             | Text containing the lyrics of the song. Supports multiline input and dynamic prompts.                                      | STRING    | Yes      | -                         |
| `seed`               | Random seed used for generation. Changing it produces different results. Default: 0.                                       | INT       | Yes      | 0 to 18446744073709551615 |
| `mode`               | full: generates melody and chords; melody: generates melody only, recommended for covers.                                  | COMBO     | Yes      | "full"<br />"melody"      |
| `max_abc_tokens`     | Maximum number of tokens generated for the ABC notation. Default: 8192. Advanced setting.                                  | INT       | Yes      | 1 to 20000                |
| `temperature`        | Controls the randomness of the generated tokens. Higher values produce more varied output. Default: 0.7. Advanced setting. | FLOAT     | Yes      | 0.0 to 5.0                |
| `top_p`              | Nucleus sampling threshold; only tokens within this cumulative probability are considered. Default: 0.9. Advanced setting. | FLOAT     | Yes      | 0.01 to 1.0               |
| `top_k`              | Limits token selection to the K most likely tokens. Default: 30. Advanced setting.                                         | INT       | Yes      | 1 to 32768                |
| `repetition_penalty` | Penalty applied to repeated tokens during generation. Default: 1.005. Advanced setting.                                    | FLOAT     | Yes      | 0.01 to 10.0              |
| `penalty_window`     | Number of recent ABC tokens used to penalize repetition. Default: 100. Advanced setting.                                   | INT       | Yes      | 1 to 20000                |
