Data Pre-processing

Convert from MusicXML

• Navigate to the data folder cd data/
• Modify the ORI_FOLDER and DES_FOLDER in 1_batch_xml2abc.py, then run this script:
  python 1_batch_xml2abc.py
  This will conver the MusicXML files into standard ABC notation files.
• Modify the ORI_FOLDER, INTERLEAVED_FOLDER, AUGMENTED_FOLDER, and EVAL_SPLIT in 2_data_preprocess.py:
  python

  1ORI_FOLDER = '' # Folder containing standard ABC notation files 2INTERLEAVED_FOLDER = '' # Output interleaved ABC notation files that are compatible with CLaMP 2 to this folder 3AUGMENTED_FOLDER = '' # On the basis of interleaved ABC, output key-augmented and rest-omitted files that are compatible with NotaGen to this folder 4EVAL_SPLIT = 0.1 # Evaluation data ratio
  then run this script:
  python 2_data_preprocess.py
  • The script will convert the standard ABC to interleaved ABC, which is compatible with CLaMP 2. The files will be under INTERLEAVED_FOLDER.
  • This script will make 15 key signature folders under the AUGMENTED_FOLDER, and output interleaved ABC notation files with rest bars omitted. This is the data representation that NotaGen adopts.
  • This script will also generate data index files for training NotaGen. It will randomly split train and eval sets according to the proportion EVAL_SPLIT defines. The index files will be named as {AUGMENTED_FOLDER}_train.jsonl and {AUGMENTED_FOLDER}_eval.jsonl.

Data Post-processing

Preview Sheets in ABC Notation

Convert to MusicXML

• Go to the data folder cd data/
• Modify the ORI_FOLDER and DES_FOLDER in 3_batch_abc2xml.py, then run this script:
  python 3_batch_abc2xml.py
  This will conver the standard/interleaved ABC notation files into MusicXML files.
