PianoFingering.jl is an innovative automatic fingering generator designed for piano scores using the Julia programming language. While it offers helpful suggestions on fingering, it’s important to note that these are for reference only, and there is no one-size-fits-all solution. This article will guide you through the installation and usage of PianoFingering.jl, along with troubleshooting tips for any bumps along the way.

Pre-requisites: Setting Up the Environment

Before diving into the main features of PianoFingering.jl, you need to prepare your system. Here are the steps:

• Copy and run the following commands to ensure you have the necessary software:
• Install Python (3.11) and Julia (1.9):

shell
python -V
julia -v

• Install the music21 library:

shell
pip3 install music21

• Clone the PianoFingering.jl repository to your computer and change the directory:

shell
cd PianoFingering.jl
julia
using Pkg
Pkg.activate(.)
Pkg.instantiate()

Congratulations! You have installed all the dependencies. You can now close your terminal.

Running the Program

Now that your environment is set up, let’s get to the fun part: running the program.

1. Place your .musicxml file into the musicxml folder. For example, let’s say you have a file called example.musicxml.
2. Change the directory back to the PianoFingering.jl folder:

shell
cd PianoFingering.jl
julia -t auto
using Pkg
Pkg.activate(.)
using PianoFingering
fingering(example.musicxml)

3. Wait for the program to finish processing. Your annotated piano score example_output.musicxml will be saved in the output folder. Note that this might take a few minutes.

Working with PIG Dataset

The Piano Fingering (PIG) dataset is a publicly available resource that can be leveraged for academic research. If you have a PIG format .txt file, place it in the pig folder and run the following command:

shell
fingering(pig_example.txt)

Converting MusicXML to PIG Format

To convert a .musicxml file to PIG format, use the command:

shell
xml_to_pig(example.musicxml)

Troubleshooting: Common Issues and Solutions

If you encounter any errors, here are some steps to troubleshoot:

• Make sure you have the correct versions of Python and Julia installed (Python 3.11 and Julia 1.9).
• If your .musicxml file does not produce any fingering, ensure it is correctly formatted and adheres to the specifications required by the program.
• For any specific issues, consider opening an issue on the repository and uploading your .musicxml file for further assistance.
