Leopold Koželuch – Piano Sonatas (A corpus of annotated scores)

Bohemian composer Leopold Koželuch had a way of repeatedly crossing paths with Mozart. Both composers were successively offered the same court position in two different instances (by the Archbishop of Salzburg and by Emperor Franz II). Koželuch's own music is however radically different, with many passages in these sonatas foreshadowing instead the tragic drama of Beethoven and von Weber. The annotations here investigate the chromatic shocks that support this tortured expression, incorporating disjunct successions and augmented sonorities that enact a significant break from the elegant and genteel vocabulary usually associated with Viennese classicism.

Getting the data

download repository as a ZIP file
download a Frictionless Datapackage that includes concatenations of the TSV files in the four folders (measures, notes, chords, and harmonies) and a JSON descriptor:
- kozeluh_sonatas.zip
- kozeluh_sonatas.datapackage.json
clone the repo: git clone https://github.com/DCMLab/kozeluh_sonatas.git

Data Formats

Each piece in this corpus is represented by five files with identical name prefixes, each in its own folder. For example, the first movement of the sonata in C, op. 8 no. 1, has the following files:

MS3/09op08no1a.mscx: Uncompressed MuseScore 3.6.2 file including the music and annotation labels.
notes/09op08no1a.notes.tsv: A table of all note heads contained in the score and their relevant features (not each of them represents an onset, some are tied together)
measures/09op08no1a.measures.tsv: A table with relevant information about the measures in the score.
chords/09op08no1a.chords.tsv: A table containing layer-wise unique onset positions with the musical markup (such as dynamics, articulation, lyrics, figured bass, etc.).
harmonies/09op08no1a.harmonies.tsv: A table of the included harmony labels (including cadences and phrases) with their positions in the score.

Each TSV file comes with its own JSON descriptor that describes the meanings and datatypes of the columns ("fields") it contains, follows the Frictionless specification, and can be used to validate and correctly load the described file.

Opening Scores

After navigating to your local copy, you can open the scores in the folder MS3 with the free and open source score editor MuseScore. Please note that the scores have been edited, annotated and tested with MuseScore 3.6.2. MuseScore 4 has since been released which renders them correctly but cannot store them back in the same format.

Opening TSV files in a spreadsheet

Tab-separated value (TSV) files are like Comma-separated value (CSV) files and can be opened with most modern text editors. However, for correctly displaying the columns, you might want to use a spreadsheet or an addon for your favourite text editor. When you use a spreadsheet such as Excel, it might annoy you by interpreting fractions as dates. This can be circumvented by using Data --> From Text/CSV or the free alternative LibreOffice Calc. Other than that, TSV data can be loaded with every modern programming language.

Loading TSV files in Python

Since the TSV files contain null values, lists, fractions, and numbers that are to be treated as strings, you may want to use this code to load any TSV files related to this repository (provided you're doing it in Python). After a quick pip install -U ms3 (requires Python 3.10 or later) you'll be able to load any TSV like this:

import ms3

labels = ms3.load_tsv("harmonies/09op08no1a.harmonies.tsv")
notes = ms3.load_tsv("notes/09op08no1a.notes.tsv")
