# [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": [ ... ]
}
}
```
