+# OpenScore String Quartets (OMR Evaluation)
+
+This dataset is derived from the [OpenScore String Quartets](https://github.com/OpenScore/StringQuartets) corpus (Gotham et al., 2023), a collection of string quartets by "long 19th century" composers. It is designed for evaluating Optical Music Recognition (OMR) systems.
+
+We extract a subset of the OpenScore String Quartets that contains both scanned images of real scores and the corresponding MusicXML ground truth. We also render clean images from the MusicXML files using MuseScore. This gives two evaluation settings:
+
+- **Camera** (`image_imslp`): scanned page images from [IMSLP](https://imslp.org/), reflecting real-world conditions (noise, aging, varying scan quality).
+- **Rendered** (`image_mscore`): clean page images rendered from the ground-truth MusicXML via MuseScore.
+
+## Dataset Structure
+
+| Column | Type | Description |
+|---|---|---|
+| `image_imslp` | `Image` | Scanned page image from IMSLP (camera) |
+| `image_mscore` | `Image` | Clean rendered page image from MuseScore |
+| `musicxml` | `string` | Ground-truth MusicXML content |
+| `filename` | `string` | Composition and page identifier |
+
+The dataset contains **252** page-level examples.
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("guangyangmusic/OpenScore-StringQuartets", split="train")
+
+# access an example
+example = ds[0]
+example["image_imslp"].show()   # scanned image
+example["image_mscore"].show()  # rendered image
+print(example["musicxml"][:200])
+print(example["filename"])
+```
