# PMB: a zero-shot benchmark for music understanding in Persian music
**13,544 clips (~20 s, 32 kHz mono MP3)** of Persian music with labels for
zero-shot evaluation of audio-language models: **genre** (7 classes),
**musical key** (24 classes; also tonic-only and mode-only granularities),
**emotion** (valence 0–100 + 3-class bins; arousal 3-class), **tempo**
(4 ordered classes), plus reference captions, Spotify popularity, and
artist/song metadata.
Derived from the PMG dataset (supervised split): the persian-pop genre was
downsampled to **1,000 distinct songs (one clip each)**, spread across 113
artists; all clips of the remaining six genres are retained.
| genre | clips |
|---|---|
| afghan pop | 5,449 |
| persian rock | 3,276 |
| classic persian pop | 2,299 |
| persian traditional | 1,277 |
| persian pop | 1,000 |
| persian alternative | 232 |
| persian neo-traditional | 11 |
## Usage
```python
from datasets import load_dataset
ds = load_dataset("keepsolid001/PMB", split="benchmark")
```
## Label provenance & caveats
- Genre/key/emotion/tempo labels are **track-level, Spotify-derived** metadata
inherited by each clip. A classical key-detection baseline
(Krumhansl-Schmuckler) agrees with the key labels at 0.37 (24-way; chance
0.04) and 0.69 (mode), validating them as benchmark gold; tempo categories
are softer (beat-tracked BPM agrees at only 0.30).
- `valence_cat` bins `valence_num` (0-100) at <40 / 40-60 / >60.
`arousal` is the dataset's own 3-way energy category.
- `caption_ref` is metadata-templated prose - suitable for attribute-coverage
metrics, not as human-written caption gold.
- Multiple clips of the same song share labels for the non-persian-pop genres;
split by `song`/`artist` to avoid leakage when training.
## Benchmark results
Eleven systems (audio-LLMs, contrastive audio-text models, and a classical DSP
baseline) have been evaluated zero-shot on this set across genre, key, emotion,
tempo, captioning (incl. cultural identification), language identification,
instrument recognition, and stem-based hallucination tests. See the paper for
full results and analysis.
