The Batik-plays-Mozart corpus

The Batik-plays-Mozart corpus is a piano performance-to-score dataset containing 12 complete Mozart Piano Sonatas (36 distinct movements) performed on a computer-monitored Bösendorfer grand piano by Viennese concert pianist Roland Batik. The performances are provided in MIDI format and note-aligned with scores in the New Mozart Edition and musicological harmony, cadence and phrase annotations previously published in The Annotated Mozart Sonatas.

This repository contains all performances in MIDI, scores in MusicXML and alignments in match file format. The audio files are commercially available.

main branch

This branch provides the curated data in the following formats:

├── match                       # alignments in match file format
├── midi                        # performance midi files
├── score_parts_annotated       # score parts corresponding to the unfolded performed score structure, aligned to the harmony, cadence and phrase annotations
├── scores                      # score musicxml files
├── annotations                 # the annotations provided by the authors of The Annotated Mozart Sonatas, linked as a submodule

curate_data branch

This branch supports linking and 'curating' the data as described in the paper.

audio_aligned_midi branch

This branch provides audio-adjusted MIDI and match files to correct MIDI-audio asynchronies due to different internal clocks resulting from different recording devices. This version should be used when working with both symbolic and audio recordings of the data.

Setup

• Install dependencies from yaml file: conda env create -f mozart_batik.yml
• Initiate the submodules if this step is not done automatically on cloning: git submodule update --init
• To create the score2score and perf2score2annotations alignments, run: python ./main.py

Structure

After running python main.py, you will get the following repository structure:

annotations             # the musicological annotations, linked as a submodule
data                    # the input data needed to create the alignments
perf2score              # the performance-score-annotations alignments
plots                   # the plots for the two experiments described in the paper
score2score             # the old inferred scores linked to the New Mozart Edition score
stats                   # some statistics on the dataset
utils                   # helper functions for creating the dataset
main.py                 
env.yml                 

score2score subdir structure

Each movement-wise directory is structured as follows:
