Music Generation with Markov Chains

Overview

This is a music generation project based on Markov Chains. The user interface takes starting notes, instrument and degree of Markov Chain as input and outputs a melody based on these parameters and probabilistic transitions between notes. The generated melody is available for playback or for download, both from the user interface.

Features

• Choose the starting notes.
• Define the instrument from General MIDI Instrument Set.
• Edit the degree of the Markov Chain for melody generation.
• Generate melodies.
• Playback and save the generated MIDI files.

functions.py

Contains core logic for:

• MIDI note conversion to pitch and vice versa.
• MIDI file handling.
• Creation of the trie
• Generating the melody

main.py

The main user interface:

• Input fields for melody generation parameters.
• Buttons for viewing instrument lists and generating melodies.
• Tkinter-based GUI setup.

ui.py

Handles user interactions:

• Error handling for incorrect inputs.
• Melody generation logic.
• Displaying instrument lists and output options.

Usage

You can find detailed setup instructions in the user_guide.md file in folder Project Documents
