Evaluation of Chord Recognition performance on the test split of the BTC dataset, reporting metrics covering chord components (Root, Thirds, Triads, etc.) and MIREX score.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Chord Recognition |
| Dataset (including any stated split) | BTC (test) |
| Metric | Root Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Root Accuracy](<https://www.sota2.com/research/sota/chord-recognition-on-btc-test.md?metric=Root%20Accuracy>): Higher is better; unit: PERCENT.

- [Maj-Min Accuracy](<https://www.sota2.com/research/sota/chord-recognition-on-btc-test.md?metric=Maj-Min%20Accuracy>): Higher is better; unit: PERCENT.

- [Thirds Accuracy](<https://www.sota2.com/research/sota/chord-recognition-on-btc-test.md?metric=Thirds%20Accuracy>): Higher is better; unit: PERCENT.

- [Triads Accuracy](<https://www.sota2.com/research/sota/chord-recognition-on-btc-test.md?metric=Triads%20Accuracy>): Higher is better; unit: PERCENT.

- [Sevenths Accuracy](<https://www.sota2.com/research/sota/chord-recognition-on-btc-test.md?metric=Sevenths%20Accuracy>): Higher is better; unit: PERCENT.

- [Tetrads Accuracy](<https://www.sota2.com/research/sota/chord-recognition-on-btc-test.md?metric=Tetrads%20Accuracy>): Higher is better; unit: PERCENT.

- [MIREX Score](<https://www.sota2.com/research/sota/chord-recognition-on-btc-test.md?metric=MIREX%20Score>): Higher is better; unit: PERCENT.
