Description
Mindful Harmony by Twiddle Coding is a browser-based music theory workstation built around the circle of fifths. Created by video game composer Sebastian Karika, it helps composers discover chord progressions by navigating an interactive circle that visualizes harmonic relationships across major, harmonic minor, and melodic minor scales.
The app goes well beyond basic chord lookup, letting you audition chords using built-in piano, strings, guitar, and chip instruments before exporting MIDI data directly into your DAW. Advanced voicing options include Drop-2, Drop-3, jazz voicings, inversions, and chord extensions up to 13ths.
A standout feature is the Auto-Modulate function, which suggests musically logical key changes based on your current position in the circle. Combined with borrowed chords, modal interchange, and template modulations, the app encourages purposeful harmonic movement rather than random experimentation.
Both MIDI input and output are supported, so you can trigger chords from a connected keyboard or route progressions to external synthesizers. The Roman numeral analysis overlay helps bridge the gap between ear-based composing and formal theory knowledge.
Mindful Harmony runs in any modern browser with no installation required. A premium tier adds cloud sync and additional features, but the core composition tools remain accessible at no cost.
