MIDI Melody Extraction

This repository contains the code for extracting the melodic line from the MIDI files of polyphonic music.

Refer to the Jupyter Notebook MIDI_MelodyExtractionTutorial.ipynb for usage tutorial. The tutorial contains codes and instructions for single and batch extraction.

Library dependency:

• mido
• numpy

Notes:

1. The python script assumes the melody is contained in the first channel of the first track of the MIDI file.

2. Current melody extraction criterion:

   • When two notes happen at the same time, only the top one will remain.

3. It works well with quantized midi.
