Pick a key and scale, then roll melody until something catches your ear. The generator writes each line note by note: it favours stepwise motion over leaps (the way most memorable melodies move), follows the contour you choose — rising, falling, arching, or wandering — packs the bars according to the density setting, leaves the occasional breath of rest, and always resolves to the tonic on the final note.

Yes — the contour control biases the melody rising, falling, arching, or wandering, and the density control (sparse, medium, busy) sets how many notes it packs into each bar. Every press of "Roll melody" generates a fresh line with those settings.
Yes — each melody is generated on your device by weighted chance, not by a model trained on anyone else’s music, so it is yours to keep and royalty-free for personal and commercial projects.
