Added metronome marks
Each movement now comes with an invisible metronome mark which naturally indicates the beat unit. The tempi roughly reflect those played by Fazıl Say in his complete recordings. The beat units have been chosen to reflect how one might conduct the music rather than the denominator of the meter (the corresponding value for which can be automatically derived).
Added chords facet
Not to be confounded with labels or chord annotations, a chord is a notational unit in which all included notes are part of the same notational layer and have the same onset and duration. Every chord has a chord_id and every note is part of a chord. These tables are used to convey score information that is not attached to a particular note, such as lyrics, staff text, dynamics and other markup.
Changes to the TSV facets
Updated filenames
The TSV files have been renamed and now come with a suffix specifying the data facet that they represent. The three facets are
- measures
- notes
- harmonies
so, for example, the file measures/01-1.tsv has been renamed to measures/01-1.measures.tsv.
Added resource descriptors
Each TSV file is now accompanied with a JSON resource descriptor following the frictionless specification for Tabular Data Resources. They can and have be used to validate the tabular data.
These files have the same names as the TSV files they describe but replacing the .tsv extension with .resource.json. For example, the file measures/01-1.tsv has the corresponding descriptor measures/01-1.resource.json.
These metadata files replace the previous csv-metadata.json files (which followed the CSVW standard) that had described the data inadequately.
Added column quarterbeats_all_endings
The quarterbeats column (also known as qstamp) that had already been available does not provide values for first or third endings, expressing the dimensions of a singular playthrough without taking into account any repeats. The newly added column quarterbeats_all_endings does not have any empty values, providing continuous positions as if each measure followed the previous one.
Renamed index column
The first column of metadata.tsv was renamed from fname to piece.
Changes to the reviewed folder
The _reviewed.mscx files compare the current set of annotation labels against those from the previous version (v2.1). They are identical, so no differences are displayed.
Wherever the MuseScore parser throws one or several warnings (e.g. because an
annotation label does not match the score very well), these warnings appear in a .warnings file. For example, the
warnings for 01-1 can be seen
in reviewed/01-1.warnings.
One goal for future versions of this dataset would be to reduce the number of warnings to the point
of addressing all of them.
Frictionless datapackage
This release is the first one that has a frictionless datapackage attached (below). It consists of
beethoven_sonatas.zip, a ZIP file containing one TSV file per facet, that corresponds to a concatenation of the TSV files in the respective folder, that isbeethoven_sonatas.expanded.tsvbeethoven_sonatas.measures.tsvbeethoven_sonatas.metadata.tsv(concatenation of a single file)beethoven_sonatas.notes.tsv
beethoven_sonatas.datapackage.json, the package descriptor.
If one has the frictionless framework installed, one can use the descriptor to validate the package using the command
frictionless validate beethoven_sonatas.datapackage.json
