12-Bar Blues in Eb Major — Chord Progression MIDI

12-Bar Blues is the backbone of blues, rock and roll, and early jazz. In Eb Major it becomes Eb – Ab – Bb. This page presets the progression tool to that key — tweak the tempo, add 7th chords or arpeggios, and download the MIDI for your DAW.

How it works

Pick a key, a scale, and one of the classic progressions, and this tool writes the chords into a MIDI file you can drop straight onto an instrument track in any DAW. Each roman numeral is voiced as a triad built from the scale — enable 7th chords for a jazzier sound, or arpeggiate to spread each chord into eighth notes. Press play preview to hear the progression before downloading. Here the tool arrives preset to 12-Bar Blues in Eb Major, so the file you download voices Eb – Ab – Bb exactly as shown above.

Popular progressions included
