B Minor Melody Generator — Free MIDI
Roll B Minor melodies from B, C#, D, E, F#, G, A and download the MIDI. Set the contour and density, keep the ones you like. Free, no sign-up.
Notes: B4 – C#5 – B4 – C#5 – D5 – F#5 – C#6 – E6 – C#6 – D6 – E6 – D6 – B5 – C#6 – B5
Without a leading tone the tonic arrives by step from above rather than being pulled up to, which is why minor melodies tend to descend to their resting note instead of climbing to it. The natural minor, or Aeolian: a flattened third, sixth and seventh. No leading tone, so it settles rather than resolving — the plainest way to sound sad. In B Minor that plays out over B, C#, D, E, F#, G, A — 2 sharps (F#, C#), the same notes as D Major. 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 B Minor, so every roll stays inside B, C#, D, E, F#, G, A and lands on B.
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 B Minor.

Frequently asked questions
What notes will a B Minor melody use?
Every generated melody draws only from the B Minor scale — B, C#, D, E, F#, G, A, which is 1 2 b3 4 5 b6 b7 against the major scale — across roughly an octave and a half starting at B4, and always resolves to the tonic B on its final note.
What makes a melody sound like Minor rather than any other scale?
Without a leading tone the tonic arrives by step from above rather than being pulled up to, which is why minor melodies tend to descend to their resting note instead of climbing to it.
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 B Minor 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.
