Melody & Ear
Step Sequencer
Build your own melodies by arranging scale notes on a step grid. Tap the grid to toggle notes, then loop-play your pattern at any tempo.
Changing key/scale keeps your pattern positions and remaps notes to the new scale.
What is this tool?
A grid where the vertical axis is pitch and the horizontal axis is time. Since you pick a scale first, only in-key notes appear — you can build great-sounding melodies without knowing any theory.
When it helps
-
A first step into melody writing
Drop notes on the grid and hear them instantly. Much faster than pen-and-paper — your ear is the feedback loop.
-
Feel the difference between scales
Switch between Pentatonic, Blues, Dorian, and more. The same pattern sounds radically different — a hands-on way to learn scales.
-
Sketch ideas before opening your DAW
Try patterns here before committing to a full production. Save time by locking an idea in audio first.
How to use
- 1 Pick Key and Scale. Beginners: try C Pentatonic Major — every note will sound right.
- 2 Tap grid cells to place notes. Vertical = pitch, horizontal = time.
- 3 Press Play to loop. You can edit live while it plays.
- 4 Hit Random to auto-generate a pattern — editing from there is a great way to learn.
- 5 Use BPM for tempo and Steps for the pattern length.
