Questions

What key are these in?
All four progressions are in B♭ major. Every chord is diatonic to that key, apart from the deliberately borrowed flat chords in the darker moods.
Can I use these in a song I sell?
Yes. Chord progressions are not protected by copyright — only a specific recording or written arrangement is. Nobody owns i–VI–III–VII.
How do I get these into my DAW?
Open the free generator, pick B♭ and Jazzy, then export the .mid and drag it onto a track in Ableton, FL Studio, Logic, Reaper or Bitwig.
