In their own words
ChordProgressions.org
ChordProgressions.org is a free browser studio for creating, hearing, analyzing, customizing, and exporting chord progressions for guitar and piano. Its tools include generators, builders, finders, identifiers, analyzers, and transposers. Guitar shapes and piano voicings can be adjusted for tuning, capo position, difficulty, inversions, and fingering. Theory views show Roman numerals, Nashville numbers, chord functions, cadence points, borrowed chords, and an estimated key with confidence. The studio accepts MIDI input and imports MusicXML, project files, and plain-text chord sheets. Browser audio analysis creates an editable chord timeline with a confidence score. Exports include MIDI, WAV, chord-chart PDF, PNG and SVG diagrams, plain text, CSV, JSON, MusicXML, and share links. Projects autosave on the device, and imported files are read locally. Practice tools loop progressions with metronome and count-in, plus ear and playing exercises in every key.
