Chord Borrower — Modal Chord Progressions Borrow chords from any mode. Build progressions that sound nothing like everyone else's. Chord Borrower turns your phone into a modal chord instrument. Pick a key, and instantly play the seven diatonic chords of that scale — then stack on chords borrowed from Dorian, Phrygian, Lydian, harmonic minor, melodic minor, and every other mode hiding inside your key. Tap through rows of chord buttons to hear how a single root note sounds across completely different modal colors, and build progressions no ordinary chord app could give you. Play in any key, any mode Choose a major or minor key, and your primary row lights up with its seven diatonic triads. Add up to six more rows, each pulled from a different mode built on that same root — the full set of major-scale modes, plus the modes of harmonic and melodic minor. Compare Ionian against Mixolydian, or drop into Phrygian dominant, all without changing key. Shape every chord your way Tap a chord button, then dial in its quality — 7th, 9th, 11th, 13th, sus2, or sus4. Each button remembers its own setting, so you can build a progression where every chord has its own color and extension, exactly as you shaped it. Choose your voice Play everything through piano, kalimba, acoustic guitar, or synth — warm, musical presets that make every chord (and every borrowed mode) sound great. Designed to inspire A single clean screen, pastel colors, soft rounded buttons, and a friendly, uncluttered layout keep the focus on your ears, not the interface. Whether you're a songwriter chasing a fresh progression, a music student exploring modal theory, or just someone who loves the sound of an unexpected chord, Chord Borrower makes modal harmony playable, visual, and fun.
