Chordyzer - Tool for musical analysis, chord extraction and database managment (Could be a real alternative to Chordify.net, but Free, Offline and Easy)

Keras project accompanying the paper "Learning Pitch-Class Representations from Score--Audio Pairs of Classical Music", ISMIR 2021.

Chordy - A tool for musical analysis, chords-keys-harmonics-rythm-BPM and all of the data management.

A configurable, multi-threaded, real-time chord detector in C++ and Python.

Chordler is an open source tool for annotating music datasets.

Mobile app library for musical chord recognition and generation

This file can recognize chords or pitch by getting audio. A Tkinter UI window is created for easy use.

This MATLAB code creates a graph of all possible four-note chords in specified scales, performs a random walk on the graph, and outputs the results to a LaTeX file using PSTricks, which the user then compiles into an eight-page exercise in chord voicings and modulation for guitar. (See the PDF file for a completed example.)
