Dataset Summary

In CLaMP: Contrastive Language-Music Pre-training for Cross-Modal Symbolic Music Information Retrieval, we introduce WikiMusicText (WikiMT), a new dataset for the evaluation of semantic search and music classification. It includes 1010 lead sheets in ABC notation sourced from Wikifonia.org, each accompanied by a title, artist, genre, and description. The title and artist information is extracted from the score, whereas the genre labels are obtained by matching keywords from the Wikipedia entries and assigned to one of the 8 classes (Jazz, Country, Folk, R&B, Pop, Rock, Dance, and Latin) that loosely mimic the GTZAN genres. The description is obtained by utilizing BART-large to summarize and clean the corresponding Wikipedia entry. Additionally, the natural language information within the ABC notation is removed.

WikiMT is a unique resource to support the evaluation of semantic search and music classification. However, it is important to acknowledge that the dataset was curated from publicly available sources, and there may be limitations concerning the accuracy and completeness of the genre and description information. Further research is needed to explore the potential biases and limitations of the dataset and to develop strategies to address them.

How to Access Music Score Metadata for ABC Notation

To access metadata related to ABC notation music scores from the WikiMT dataset, follow these steps:

1. Locate the xml2abc.py script:

   • Visit https://wim.vree.org/svgParse/xml2abc.html.
   • You will find a python script named xml2abc.py-{version number}.zip. Copy the link of this zip file.

2. Locate the Wikifonia MusicXML Data:

   • Visit the discussion: Download for Wikifonia all 6,675 Lead Sheets.
   • You will find the download link of a zip file named Wikifonia.zip for the Wikifonia dataset in MusicXML format (with a.mxl extension). Copy the link of this zip file.

3. Run the Provided Code: Once you have found the Wikifonia MusicXML data link, execute the provided Python code below. This code will handle the following tasks:

   • Automatically download the "xml2abc.py" conversion script, with special thanks to the author, Willem (Wim).
   • Automatically download the "wikimusictext.jsonl" dataset, which contains metadata associated with music scores.
   • Prompt you for the xml2abc/Wikifonia URL, as follows:

   Enter the xml2abc/Wikifonia URL: [Paste your URL here]
   

   Paste the URL pointing to the xml2abc.py-{version number}.zip or Wikifonia.zip file and press Enter.

The below code will take care of downloading, processing, and extracting the music score metadata, making it ready for your research or applications.
