The Wagner Ring Dataset (WRD) is a multi-modal and multi-version annotated dataset built on Wagner's tetralogy Der Ring des Nibelungen. The Ring comprises four operas (or music dramas) organized into eleven acts and 21939 measures. Concerning the primary material (raw data), the WRD provides score representations in various modalities and 16 recorded performances (three of them publicly available). For all versions (score and audio), we provide comprehensive annotations of measure positions, note events, singing voice regions including singers and lyrics as well as scene, key, and time signature regions. The WRD is organized as follows: 01_RawData score_pdf_IMSLP score_sibelius score_pdf_sibelius score_musicxml score_midi audio_wav 02_Annotations ann_score_singing ann_score_timesignatures ann_score_keysignatures ann_score_scenes ann_audio_measure ann_audio_note ann_audio_singing ann_audio_timesignatures ann_audio_keysignatures ann_audio_scenes 03_ExtraMaterial Scripts and tables for merging individual CD tracks, ...
