Continuo vs Chord Borrower

Type the changes. Get the bassline. Most bassline tools ask you for a scale. Continuo asks for your chords. Type a progression — slash chords and all — pick a style, and Continuo writes a line that actually plays those changes: chord tones on the strong beats, approach notes into the next chord, and a register that sits where a bass player would sit. HOW IT WORKS • Type your changes one bar at a time, separated by | — or start from one of 18 built-in sets: 12-bar blues, rhythm changes, ii-V-I, doo-wop, montuno vamp, bossa turnaround, 7/8 vamp and more. • Slash chords like Am/C pin the bass note, so the line plays exactly what you wrote. • Pick a style, then shape it: Density (sparse to busy), Motion (plain roots to passing and chromatic tones), and Swing (straight to triplet). • Tap Next take to cycle through ranked alternatives, best first. Tap any chord in the strip to swap, move, or stretch it — the line rewrites around your edit. • Undo steps back over anything that changed the line — an edit, a preset, an import, a take, even a slider. WHAT'S INSIDE • Seven styles: root and fifth, walking, funk/R&B, tumbao, bossa nova, reggae one-drop, and Motown. • Seven instruments that change what gets played, not just the tone: 4-, 5- and 6-string bass guitar, upright, 808/sub, synth bass, and chiptune. • Any time signature — 4/4, 3/4, 6/8, 9/8, 12/8, 5/4, 7/8, 5/8, 11/8 and more. Every style works in every meter. • Import changes from a MIDI or MusicXML file. • MIDI export, optionally with a reference chord track — plus MusicXML with chord symbols for MuseScore, Sibelius, Dorico, and Finale. • A bass-clef notation preview with chord symbols. • Fully offline. No account, no sign-in, no ads, no in-app purchases. • Private by design — Continuo collects nothing. Your music never leaves your device unless you export it. Continuo is by Songdeed. Pairs with Mediant, our chord-progression app.

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.
