# [ACL 2025] SongCompose Dataset 

This repository hosts the official dataset used in **[SongComposer](https://arxiv.org/abs/2402.17645)**, a system designed for aligning lyrics and melody for LLMs-based vocal composition.

## 🌟 Overview

The dataset includes three types of aligned resources, grouped by language (English and Chinese):

- `lyric`: Unpaired lyrics in English and Chinese
- `melody`: Unpaired melodies (note sequences and durations)
- `pair`: Aligned lyric-melody pairs with note durations, rest durations, structures, and tempo (bpm)

Each top-level key in the JSON corresponds to a category (`lyric`, `melody`, `pair`), and each of them has nested keys `en` and `cn` for language split.

## 📂 Structure

Example format:

```json
{
  "pair": {
    "en": [
      {
        "lyrics": "...",
        "notes": [...],
        "notes_duration": [...],
        "rest_duration": [...],
        "bpm": 120
      },
      ...
    ],
    "cn": [ ... ]
  },
  "melody": {
    "all": [ ... ],
  },
  "lyric": {
    "en": [ ... ],
    "cn": [ ... ]
  }
}
```
