Roll D Blues melodies from D, F, G, Ab, A, C and download the MIDI. Set the contour and density, keep the ones you like. Free, no sign-up.
Melodies lean on the b5 as a passing note between the fourth and the fifth rather than landing on it, and the same short phrase is usually repeated with its ending changed — call and response inside one line. The minor pentatonic with a flattened fifth wedged between the fourth and the fifth — the "blue note" that gives the scale its ache when it is bent or passed through rather than sat on. In D Blues that plays out over D, F, G, Ab, A, C — 1 flat (Bb), plus Ab written in. Set a contour and a density, roll until a line catches your ear, and download exactly what you heard as MIDI.

Key signature: 1 flat (Bb), plus Ab written in.
W is a whole step (two semitones), H a half step (one), W+H a three-semitone jump. The pattern adds up to the octave.
The tonic is the darkest key; every other highlighted key belongs to the scale.
blues, rock and roll, soul, funk and jazz solos; the default vocabulary of guitar lead playing.
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 D Blues, so every roll stays inside D, F, G, Ab, A, C and lands on D.
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 D Blues.
Or head back to the melody generator to build any combination yourself.
Every generated melody draws only from the D Blues scale — D, F, G, Ab, A, C, which is 1 b3 4 b5 5 b7 against the major scale — across roughly an octave and a half starting at D4, and always resolves to the tonic D on its 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.
