Our verdict on Harmony Pro
Harmony Pro is a free harmony exploration tool for composers and producers who want to enter chords, inspect their harmonic structure, and develop progressions. It displays detected chords, supports reverse lookup, and lets users explore inversions, voicings, octave placement, and common tones. Progressions can be built, played back, listened to, and compared. The browser-based application and downloadable macOS and Windows versions give it a useful fit for desktop-focused songwriting and production workflows.
The Free plan includes chord and progression exploration, a suggestion engine, and voicing exploration. Its context-aware suggestions can follow configurable musical directions and styles, helping users investigate possible next chords rather than relying only on manual entry. Keyboard, guitar, and sheet views present the same harmonic material in different forms, while locked-note and common-tone controls support more focused voicing decisions. Audio playback makes it possible to compare harmonic options directly within the tool.
Harmony Pro’s main strength is the depth of its focused chord workspace: it combines progression building, reverse lookup, voicing controls, detected-chord display, and playback without adding paid tiers or an AI layer. It should suit composers and producers who want free desktop software for studying harmony and shaping chord sequences. Users looking for verified export, integrations with other music software, native mobile access, or AI-assisted generation should choose an alternative built around those needs instead.
