Build progressions by Roman-numeral degree
Pick a key and time signature, then add chords by scale degree: I, IV, V, vi, ii, iii, vii°. Because everything is relative to the key, the same progression makes sense whether you are in C or F♯, and transposing is a single click.
Each chord is colour-coded by its degree, so you can see the harmony of a whole section at a glance instead of decoding a wall of chord symbols.
Hear it with real instruments
Play any chord or the whole progression back with sampled piano, acoustic guitar, electric bass, or ukulele. Set per-chord beats so the playback follows your actual rhythm, and loop a section while you experiment.
Stay diatonic, or break the rules on purpose
Diatonic suggestions show you which chords belong in the key, so you can stack a believable progression fast. Want tension? Drop in a borrowed chord and the colour coding makes the outside chord obvious.
Generate chord progressions with AI
Stuck on the next move? The built-in chord progression generator suggests the next chord or a full progression in your key and genre, then you tweak what comes back. Every plan includes a few AI chord suggestions a day, and Pro raises the daily limit.
Frequently asked questions
Is the chord maker free?
Yes. You can make progressions, hear them with instrument samples, and save two songs on the free plan with no credit card. AI chord suggestions come with a small daily limit on free; Pro raises that limit and unlocks unlimited songs.
How is a chord maker different from a chord progression generator?
A chord maker lets you build progressions yourself, chord by chord; a generator writes one for you. The LandChords ChordMaker does both: tap chords in by scale degree, or ask the AI to generate a progression in your key and genre and edit from there.
Do I need music theory to use it?
No. Diatonic suggestions show you which chords belong in your key, and the colour-coded Roman numerals make the relationships visible as you go, so beginners can build progressions by ear while picking up the theory naturally.
Do I need to install anything?
No. LandChords runs entirely in your browser on desktop and mobile. There is nothing to download or install.
Can I transpose a progression to another key?
Yes. Because chords are stored by Roman-numeral degree, transposing the whole song to any key is a single click.
