Orfeo is a free, open-source desktop app that turns MIDI files into an interactive piano lesson: notes fall onto a virtual keyboard in real time, keys light up as they play, and you can slow down, loop, transpose, and explore any passage at your own pace. Real-time chord detection, hand-coloured keys, interactive chord and scale explorers, a full mixer, and per-note editing — with a piano roll that looks like it was built this decade.
WhatChord is an interactive chord identification, key detection, and harmony exploration app. Identify voicings from live Bluetooth or USB MIDI input or manual note entry, follow the key as you play, then explore chords, scales, keyboard patterns, and harmonic context. It is optimized for speed, accuracy, and musician-expected naming, favoring stable, conventional interpretations over simple note-matching.
Tksolfege is an ear training program for learning to recognize chords, intervals, perform rhythm dictation, solfege dictation and singing solfege sequences. The program requires Tcl/Tk 8.4, however the Windows executable has Tcl/Tk builtin.
Features:
The program contains ear training exercises for the identification of chords, musical intervals, key signatures, musical scales, and cadences.
This software can be used to search scales & chords from a large and expandable database (XML). Thanks to the jmusic project (jmusic.sourceforge.io), this is also possible to generate music starting from these scales & chords and export the result to MIDI file.
