How it works
Make a melody online in three steps
- 1
Pick a key and scale
Choose a root note and a scale at the top of the piano roll. The rows that belong to your key light up, so every note you place already sounds right.
- 2
Draw or generate the melody
Click a cell to place a note and drag its edge to stretch it. Or press Generate Melody and let the piano melody generator write a progression you can edit.
- 3
Export to MIDI or WAV
Hit Play All to audition the loop, then export a .mid file for your DAW or a finished WAV — no account, no watermark, no limits.
What you get
A free melody maker that behaves like a real DAW
Most browser tools give you a toy grid. This one gives you the piano roll you already know — and hands you a MIDI file at the end of it.
Melody generator from chords
Turn on Chord Help and one click paints a full diatonic chord that is locked to your key. Build a progression first, then let the generator write a melody on top of it — the classic way to start a song.
Export MIDI and WAV
Download a standard .mid file and drag it straight into FL Studio, Ableton Live, Logic Pro, GarageBand or Reaper. Prefer audio? Render the loop as a high-quality WAV in the same Export menu.
Every instrument unlocked
Pianos, keys, plucks and pads — the whole instrument list is free. Switch sounds mid-melody and playback updates instantly, so you can hear the idea with the right timbre before you export.
An online melody maker with nothing in the way
Every idea starts the same way: you hear something and you need to get it down before it disappears. That is what this online melody maker is for. The page loads straight into a working piano roll online — no account screen, no trial timer, no plugin installer. Click a cell, hear the note, drag its right edge to make it longer, and keep going until the bar sounds like the thing in your head.
Notes are colour-coded by pitch and each block shows its own rhythmic value, so a stretched note reads as a half or a whole note instead of an anonymous bar. Green markers divide the grid into sections, which makes it easy to sketch a four-bar idea, then a variation, then the part that ties them together.
Generate a melody from chords
If you would rather start from harmony, set your key and switch on Chord Help. One click then places a full diatonic chord instead of a single note, so you can lay down a progression in a few seconds. Press Generate Melody and the piano melody generator writes a line over that progression — a starting point you can drag, trim and rewrite rather than a black box you have to accept.
Take it into your DAW
A melody is only useful if it leaves the browser. The Export menu gives you a standard .mid file that drops into FL Studio, Ableton Live, Logic Pro, GarageBand or Reaper with your note lengths and timing intact — or a rendered WAV if you just want the audio. Both are free, unwatermarked, and yours to use in any project.
