# SheetSage2AudioToABC - ComfyUI Built-in Node Documentation

> This node transcribes vocal and instrumental melodies from music into ABC notation, a text-based format for writing down musical scores.

This node transcribes vocal and instrumental melodies from music into ABC notation, a text-based format for writing down musical scores. It analyzes the connected audio and returns the resulting notation as text, which can then be fed into the YuE2 Generate Music node using the matching mode.

## Inputs

| Parameter       | Description                                                                                                               | Data Type      | Required | Range                    |
| --------------- | ------------------------------------------------------------------------------------------------------------------------- | -------------- | -------- | ------------------------ |
| `audio_encoder` | The audio encoder model used to analyze the audio and produce the ABC notation.                                           | AUDIO\_ENCODER | Yes      | -                        |
| `audio`         | The music audio to transcribe into ABC notation.                                                                          | AUDIO          | Yes      | -                        |
