Chords Weaver: find chords by ear
A chord instrument you play by ear, right in your browser. Pick a note on the keyboard and it shows the chords that fit. Two pads let you shape the voicing and suggest where to go next, and the progression you build on the timeline plays back with arpeggios and grooves.
What you can do
- Find the chords that fit the note you pick
- Shape each voicing: spread, inversion, octave
- Follow next-chord suggestions, resolving or adding tension
- Play the loop with arpeggios, block grooves and strums
- Export to MIDI, WAV or text, or send live MIDI out (Pro unlock)
On your phone
Chords Weaver is also on iPhone and Android: App Store, Google Play. I make it on my own: write me from the support page. If you like it, check out Chords Explorer too.
Questions
What is Chords Weaver?
Chords Weaver is a chord instrument I built to find chords by ear. You pick a note on the keyboard and it shows the chords that fit. Two pads then let you shape the voicing and suggest where to go next, and the progression you build plays back with arpeggios and grooves.
Is Chords Weaver free?
Yes. Weaving, voicings, playback and saving are free, with no ads and no subscription. A one-time Pro unlock adds MIDI, WAV and text export, live MIDI out and custom chord types, and it's how you can support my work on the app.
Can I use Chords Weaver in my browser without installing it?
Yes, the web version runs right here at chords-weaver.me, nothing to install. The iPhone and Android apps are on the App Store and Google Play. The web version and the phone apps each have their own Pro unlock.
Does Chords Weaver work with my DAW or hardware synths?
Yes. With Pro you can export a progression as a MIDI file for your DAW, or send it live over MIDI to a DAW or a hardware synth, with a MIDI clock so they stay in time. In the browser, live MIDI out needs Web MIDI support, which Chrome has.
Do I need an account to use Chords Weaver?
No. Signing in with email, Google or Apple is optional. It only syncs your saved progressions across your devices.
