ChoCo: the Chord Corpus

Overview

We are happy to announce the new release of ChoCo, which has now reached v1.0.0. This ChoCo release includes updates and improvements to ChoCo's licensing and symbolic collections. We have adopted a dual licensing scheme for ChoCo's data, and regenerated all symbolic collections following improvements to the JAMifier, providing a more meaningful and complete version of JAMS files.

📄 Licensing Updates

We have adopted a dual licensing scheme for ChoCo's data. Only three subsets are released using the CC-BY-NC-SA 4.0 license, while all the others follow the CC-BY 4.0 license. We include the LICENSE.md file in the release which contains all the details.

🎼 Symbolic Collection Updates

All symbolic collections have been regenerated following improvements to the JAMifier. Measures and beats now always start from 1, and time signatures are included in the JAMS files. Temporal information such as onset and duration is now expressed in measures and beats, making our JAMS files and KG more meaningful.

❇️ Knowledge Graph Updates

The Knowledge Graph was regenerated to reflect the changes made to the JAMifier and the JAMS files produced.
