melody-features 1.0.6

A Python package for computing tonnes of melodic features found in computational musicology literature.

Melody-Features

Overview

This is a Python package designed to facilitate the use of many different melody analyis tools.

The main goal of this package is to consolidate a wide range of features from the computational melody analysis literature into a single place, in a single language.

This package is strictly for monophonic melodies - it will not compute any features for polyphonic music!

Included Contributions

Included in the package are contributions from:

• FANTASTIC (Müllensiefen, 2009)
• SIMILE (Müllensiefen & Frieler, 2006)
• melsim (Silas & Frieler, n.d.)
• jSymbolic2 (McKay & Fujinaga, 2006)
• IDyOM (Pearce, 2005)
• MIDI Toolbox (Eerola & Toiviainen, 2004)

Melody Features Summary

This package provides over 200 features from various computational melody analysis frameworks. For a comprehensive, interactive table with search and sorting capabilities, refer to:

Interactive Features Table

The interactive table allows you to:

• Search features by name, implementation, or description
• Sort by any column (Name, Implementation, Type, etc.)
• Browse all features with detailed descriptions and references

Installation

# using pip
pip install melody-features

# or clone the repository
git clone https://github.com/dmwhyatt/melody-features.git
cd melody-features

# Install in development mode
pip install -e .

Quick Start

The feature set can be easily accessed using the top-level function get_all_features. Here's a basic example:

from melody_features import get_all_features

# Extract features from a directory of MIDI files, a single MIDI file
# or a list of paths to MIDI files
results = get_all_features(input="path/to/your/midi/files")

# Print the result of all feature calculations
print(results.iloc[:1,].to_json(indent=4, orient="records"))

By default, this function will produce a Pandas DataFrame containing the tabulated features, using the Essen Folksong Collection as the reference corpus.

This function can be customised in a number of ways, please see notebooks/example.ipynb for a detailed breakdown.

Melsim

Melsim is an R package for computing the similarity between two or more melodies. It is currently under development by Seb Silas and Klaus Frieler (https://github.com/sebsilas/melsim)

It is included with this feature set through a wrapper approach - take a look at example.py and the supplied MIDI files.

Since calculating similarities is highly modular in Melsim, we leave the user to decide how they wish to construct comparisons. Melsim is not run as part of the get_all_features function.

Available Corpora

The package comes with an example corpus, a MIDI conversion of the well-known Essen Folksong Collection (Eck, 2024; Schaffrath, 1995).
