You can make chords without playing piano: describe the mood and the key to Veena's CoProducer, your personal music producer, and it writes the progression as real MIDI with proper voicings, on a piano, an Electric Piano or a pad. Then you edit it note by note in the piano roll with a mouse. Free, in your browser.
Plenty of producers have great ears and no keyboard chops. You know the chorus needs to lift. You can hear the warm, jazzy chord under the hook in your head. Then you open a piano roll, stack three notes and get something that sounds like a ringtone.
The problem is rarely the chord names. It's the voicing: which note is on the bottom, how wide the stack is, what the top note does from one chord to the next. That's the part pianists learn through their fingers, and it's the difference between a progression that sounds played and one that sounds typed.
It's also the most common wall there is. In Veena's own data, "chord progression" is the single most common phrase in first requests.
Open the studio, sign in with Google and tell CoProducer what you hear. You can brief it like a listener or like a theory nerd; both work:
"Write a 4-bar chord progression for a late-night neo-soul track at 84 BPM in E-flat major: warm, a little bittersweet, with 7ths and 9ths, on Electric Piano. Use smooth inversions so the top note moves by step."
Or just: "ii–V–I in C with 9ths, on Electric Piano." CoProducer writes the part and offers 3 options in one carousel. Hover a card to hear it, press Enter to add it, or ask for More Options.
The first progression is a draft. Shape the voicings the way a keyboard player would:
- "Re-voice the chorus so the top note climbs."
- "Spread the chords wider for the last 8 bars."
- "Use inversions so the verse chords move smoothly."
- "Add 9ths to the verse and keep the chorus plain."
- "Swap the Electric Piano for String Ensemble." The notes stay; the sound changes.
One Ctrl+Z (Cmd+Z on a Mac) undoes any change, so try the bold version first.
Double-click the chord clip to open the piano roll and switch on Show Note Names. Drag a note up or down to change one voice; select a whole chord and press Ctrl+↑ or Ctrl+↓ (Cmd on a Mac) to move it an octave. Set snap to a bar or a beat so chords land on the grid, and drag velocities down for a softer inner voice.
If the melody comes first, hum it. Record the hum, drag it into the CoProducer panel and ask for "chords under my melody." It transcribes your hum into editable MIDI, then writes a progression that fits the notes you sang. More on that in can AI create chords from a melody.
Here's one chord, C major 7 (C, E, G, B), stacked five ways. Ask CoProducer for any of these by name, or drag the notes into place yourself:
| Voicing | Notes, bottom to top | What it sounds like |
|---|
| Root position, closed | C3 E3 G3 B3 | Solid, a little boxy |
| First inversion | E3 G3 B3 C4 | Lighter, with E in the bass |
| Open, spread | C3 G3 B3 E4 | Wide and expensive, the "record" sound |
| Shell | C3 B3 E4 | Just root, 7th and 3rd: jazz piano, leaves room for the bass |
| With a 9th | C3 G3 B3 D4 E4 | Neo-soul warmth, the chord becomes Cmaj9 |
The trick pianists use without thinking: keep the top notes close from chord to chord. When the top voice moves by a step instead of a leap, the progression sounds like one hand playing it, not four chords glued together.

| Numerals | In C major | The feel | Brief for CoProducer |
|---|
| I–V–vi–IV | C, G, Am, F | The pop anthem | "I–V–vi–IV in C on Acoustic Grand Piano, big and open" |
| vi–IV–I–V | Am, F, C, G | Bittersweet, minor-leaning | "vi–IV–I–V in C, soft pads, slow and wistful" |
| ii–V–I | Dm7, G7, Cmaj7 | Jazz and neo-soul resolution | "ii–V–I in C with 9ths on Electric Piano" |
| IVmaj7–iii7–ii7–Imaj7 | Fmaj7, Em7, Dm7, Cmaj7 | Lo-fi, stepping down | "Fmaj7, Em7, Dm7, Cmaj7 on Electric Piano with lazy timing" |
Change the key in the brief and CoProducer transposes the idea. For a whole library by mood, see sad chord progressions and neo-soul chord progressions, or open the chord progression generator for one-line briefs by genre.
Want to play them yourself one day? Your computer keyboard is a piano in Veena: the row from A to the apostrophe plays white keys, W to the right bracket plays black keys, and Z and X change octave. Record a take, then ask CoProducer to quantize it.
Veena writes the chords, voices them, builds the song around them and keeps every note editable, free in a browser. Here's what the usual alternatives cost you, from each company's own pages.
- Ableton Live: chord generators start at $349. Live's MIDI Generators, Stacks among them, aren't in the $99 Intro edition; they start with Standard at $349 (Ableton's compare page, September 2026).
- Logic Pro: a keyboard player, on a Mac only. Session Players "lay down polished synth, bass, keyboard, and drum grooves" (Apple, September 2026), inside a $199.99 app, or $12.99 a month, that needs a Mac with Apple silicon.
- Waveform Pro: suggestions you pay for twice. Tracktion's Assistant suggests chords, but "it won't do anything until you add an API key in settings," so you pay your AI provider per use on top of Pro bundles from $249 (Tracktion, September 2026). It's "not a one-prompt 'make me a song' tool."
- Muse: MIDI beside another DAW. Muse is an AI MIDI composer built to sit alongside your existing DAW, and commercial export needs Pro, at $15 a month (Muse's pricing page, September 2026).
- Band-in-a-Box: you have to know the chords first. It builds a backing band from the chord symbols you type, for $129 and a 35 GB download on Windows (PG Music, September 2026).
| Veena | Ableton Live | Logic Pro | Waveform Pro | Muse |
|---|
| Price to start | Free | $99 Intro; generators from $349 | $199.99, or $12.99 a month | Bundles from $249, plus your own AI key | Free, around 5 credits a day |
| Who writes the chords | CoProducer, from plain words, 3 options | The Stacks generator, from Standard | Session Players | Assistant suggestions | Its AI agent, as MIDI |
| The song around the chords | Drums, bass, melody and mix, in the same project | Built by hand | Session Players, on a Mac | "Not a one-prompt 'make me a song' tool" | Made in a second DAW |
Hearing the right chord is the musical skill. Finding it on a keyboard is mechanics, and mechanics are what a producer can help with. Describe the progression you hear tonight, pick the voicing that gives you chills, and build the song on it. When you want a tune on top, the melody generator is one brief away.
