What ChordProgressions.org is
ChordProgressions.org is a free browser-based studio for creating, hearing, analyzing, and exporting chord progressions for guitar and piano. Its tools include a generator, builder, finder, identifier, analyzer, and transposer. Users can generate guitar shapes and piano voicings, adjusting settings such as tuning, capo position, difficulty, inversions, and fingering. Theory analysis can display Roman numerals, Nashville numbers, chord functions, cadence points, borrowed chords, and a key estimate with a confidence rating. The studio accepts MIDI input and imports MusicXML, project files, and plain-text chord sheets. Audio analysis runs in the browser and produces an editable chord timeline with a confidence score. Export choices include MIDI, WAV, chord chart PDF, PNG and SVG diagrams, plain text, CSV, JSON, MusicXML, and share links. Projects autosave in the browser and stay on the device; imported files are read locally rather than uploaded. The practice tool loops progressions with a metronome and count-in and offers ear-recognition and playing practice in every key. JavaScript is required for studio playback and editing.
