[new chord progression] 5400 unique 12-chords progressions

[asigalov61]

Hello everyone!

First of all, I wanted to thank @ldrolez and other contributors for free-midi-chords! It's awesome and I use it a lot in my research and work! :)
 
I have been meaning to contribute to free-midi-chords for a while now so I will get right to it:

** Which Chord progression would you like to add to the pack? **

5400_unique_12_chords_progressions.json

This Json file contains 5400 unique 12-chords progressions which were extracted from one of my MIDI datasets.

While some progressions may already be a part of free-midi-chords, most of them should be unique. And I highly hope it will help to expand/add to free-midi-chords collection.

The chords progressions are in form of a python list of lists of chords qualities. I apologize for not using the standard notation. However, it should be easy to convert them to free-midi-chords format.

The chords progressions in the list were sorted from most common to least common.

You can easily read the file like so:

import json

# Open and read the JSON file
with open('5400_unique_12_chords_progressions.json', 'r') as file:
    chords = json.load(file)

# Print first 10 chords
print(chords[:10])

This is WIP and I plan to add additional data and features to this chords collection.

Hope this is somehow useful.

Most sincerely,

Alex

Hi Alex! Thanks for your contribution. It seems that the json contains intervals? I'll need to find a way to convert them to my notation.

@ldrolez You are very welcome :)

Yes, it would be great if there was a function to convert chords (intervals) into free-midi-chords notation and back.

Thank you.
