A MIDI melody generator supporting multiple musical genres

Musical MIDI Generator

A Python-based MIDI melody generator that creates musical compositions across different genres with sophisticated chord progressions, melodic patterns, and basslines.

Features

• Multiple genre support including:
  • Pop/Rock
  • Jazz
  • Blues
  • Latin
  • Folk/Acoustic
  • Electronic
  • Epic/Film Score
  • R&B/Soul
• Intelligent chord progression generation based on genre
• Dynamic melody creation with genre-specific patterns
• Accompanying bassline generation
• Support for different musical keys
• Multi-track MIDI output (melody, chords, and bass)
• Genre-appropriate rhythmic patterns
• Verse and chorus section generation

Installation

You can install this package in two ways:

1. Using pip (Recommended)

pip install --index-url https://maven.pkg.github.com/JDCurry/midi-melody-generator/ midimelody

2. From source

git clone https://github.com/JDCurry/midi-melody-generator.git
cd midi-melody-generator
pip install -e .

Usage

As a Python Package

from midimelody import generate_midi

# Generate a new MIDI composition
generate_midi()

From Command Line

If installed from source, you can run directly:

python melody_generator.py

Follow the interactive prompts to:

1. Select a musical key (C, C#/Db, D, etc.)
2. Choose a genre
3. The program will generate a MIDI file with a unique name in your current directory

How It Works

The generator creates music in three layers:

1. Chord Progression: Genre-specific chord progressions that form the harmonic foundation
2. Melody: Intelligent melody generation that follows chord tones and scale degrees
3. Bassline: Complementary bass patterns that match the genre and harmony

Each genre has its own characteristics:

• Pop/Rock: Standard chord progressions with catchy melodic patterns
• Jazz: Sophisticated harmony with extended chords
• Blues: Traditional 12-bar patterns with blue notes
• Latin: Syncopated rhythms and specific harmonic movements
• Folk: Simple, traditional progressions
• Electronic: Modern, repetitive patterns
• Epic/Film Score: Dramatic progressions and wide melodic ranges
• R&B/Soul: Soulful progressions with rhythmic emphasis

Development

Setting up for development

1. Clone the repository:

git clone https://github.com/JDCurry/midi-melody-generator.git
cd midi-melody-generator

2. Create a virtual environment:

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install development dependencies:

pip install -e ".[dev]"

Running Tests

python -m unittest tests/test_generator.py
