The flattened seventh removes the pull home, so melodies circle rather than cadence — phrases end on the flat seventh or the fifth and simply start again, which is what makes a vamp. Major with a flattened seventh. Losing the leading tone drops the pull home, which is what makes it sound like a groove rather than a cadence. In Bb Mixolydian that plays out over Bb, C, D, Eb, F, G, Ab — 3 flats (Bb, Eb, Ab). Set a contour and a density, roll until a line catches your ear, and download exactly what you heard as MIDI.

How it works
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. Press play preview to hear the exact notes the download writes. This page arrives preset to Bb Mixolydian, so every roll stays inside Bb, C, D, Eb, F, G, Ab and lands on Bb.
What can you do with a melody MIDI file?
- Drop it onto any instrument track in your DAW as a topline, hook, or counter-melody starting point.
- Edit the notes on the piano roll — keep the phrase you like, rewrite the rest.
- Roll a few variations in the same key and splice the best bars together.
A generated melody is a starting point, not a finished song. For complete arrangements — melody, chords, bass and drums that belong together — open the MIDI Maker studio and generate a full track in Bb Mixolydian.

Frequently asked questions
What notes will a Bb Mixolydian melody use?
Every generated melody draws only from the Bb Mixolydian scale — Bb, C, D, Eb, F, G, Ab, which is 1 2 3 4 5 6 b7 against the major scale — across roughly an octave and a half starting at Bb4, and always resolves to the tonic Bb on its final note.
What makes a melody sound like Mixolydian rather than any other scale?
The flattened seventh removes the pull home, so melodies circle rather than cadence — phrases end on the flat seventh or the fifth and simply start again, which is what makes a vamp.
Can I control the shape of the melody?
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.
Is the generated Bb Mixolydian melody royalty-free?
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.
