Tonality classicalDB Dataset

The Tonality classicalDB Dataset includes 880 classical musical pieces across different styles from s.XVII to s.XX annotated with single-key labels. Tonality classicalDB Dataset was created as part of: Gómez, E. (2006). PhD Thesis. Tonal description of music audio signals. Department of Information and Communication Technologies. This dataset is mainly intended to assess the performance of computational key estimation algorithms in classical music. 2020 note: The audios are privates. If you don't have the original audio collection, you could create it from your private collection because most of the recordings are well known. To this end, we provide musicbrainz metadata. Moreover, we have added the spectrum and HPCP chromagram of each audio. This dataset can be used with mirdata library: https://github.com/mir-dataset-loaders/mirdata Spectrum features have been computed as is shown here: https://github.com/mir-dataset-loaders/mirdata-notebooks/blob/master/Tonality_classicalDB/ClassicalDB_spectrum_features.ipynb HPCP chromagram has been computed as is shown here: https://github.com/mir-dataset-loaders/mirdata-notebooks/blob/master/Tonality_classicalDB/ClassicalDB_HPCP_features.ipynb Musicbrainz metadata has been computed as is shown here: https://github.com/mir-dataset-loaders/mirdata-notebooks/blob/master/Tonality_classicalDB/ClassicalDB_musicbrainz_metadata.ipynb

调性古典数据库（Tonality classicalDB）包含880首来自17至20世纪不同风格的古典音乐作品，所有作品均标注有单调式标签。本数据集的构建源于Gómez, E.（2006年）的博士学位论文《音乐音频信号的调性描述》，所属单位为信息与通信技术系。本数据集主要用于评估古典音乐场景下计算性调式估计算法的性能。2020年补充说明：原始音频文件为非公开资源。由于多数录音均为广为人知的作品，若您未持有原始音频库，可通过自有非公开音频资源自行构建所需音频集。为此，我们提供了MusicBrainz元数据。此外，我们还为每条音频添加了频谱（spectrum）与HPCP色度图（HPCP chromagram）。本数据集可配合mirdata库使用：https://github.com/mir-dataset-loaders/mirdata。频谱特征的计算方法详见以下链接：https://github.com/mir-dataset-loaders/mirdata-notebooks/blob/master/Tonality_classicalDB/ClassicalDB_spectrum_features.ipynb。HPCP色度图的计算方法详见以下链接：https://github.com/mir-dataset-loaders/mirdata-notebooks/blob/master/Tonality_classicalDB/ClassicalDB_HPCP_features.ipynb。MusicBrainz元数据的计算方法详见以下链接：https://github.com/mir-dataset-loaders/mirdata-notebooks/blob/master/Tonality_classicalDB/ClassicalDB_musicbrainz_metadata.ipynb
