Research Corpora

Most of the research in CompMusic is done by studying five research corpora [Serra, 2014], all of then available from Dunya. These research corpora are not fixed, they are data collections from various sources that evolve and grow. From these corpora we create fixed test corpora (datasets) to carry out specific experiments. Here are the links to our currently available components of each corpus.

These metadata can be easily accessed through our Dunya API using the MusicBrainz unique identifier (MBID) of the recordings.
  • Lyrics: Lyrics are obtained from open repositories in the web, mainly 京剧艺术 and 中国京剧戏考.

Nevertheless, there is some cultural specific metadata that cannot be stored in MusicBrainz, such as the nawba, the tab', the mizán, the music form and the start and end time stamps of each section of the recordings. This metadata is stored in our own dataset and it can be easily accessed through our Dunya API using the MusicBrainz unique identifier (MBID) of the recordings.
