When to use it
The 12-bar blues progression in F major feels bluesy, grounded and driving, and it is used most in blues, rock and roll and R&B. It stays on dominant 7th chords for twelve bars, with the IV in the middle and the V turnaround at the end. That feel is the reason to choose this progression: when the music needs that mood, this sequence delivers it with the least effort, because the chords do the emotional work for you.
Over the 12-bar blues progression in F major, the scales that fit best are the F major scale, F minor pentatonic scale, F blues scale. The major scale fits the major chords, the minor pentatonic fits almost everything in the progression, and the blues scale adds the flattened notes that suit the dominant 7th chords where the progression has them. Start by soloing with the minor pentatonic scale over the whole progression, then try the major scale over the tonic chord and listen to how the colour changes. The Chord Progression Builder lets you hear the 12-bar blues progression in F major in any key, and the Progression Finder identifies a progression from its chords.
Variations
Quick-change blues: F7 – A#7 – F7 – F7 – A#7 – A#7 – F7 – F7 – C7 – A#7 – F7 – C7. Put the IV7 chord in bar 2 as well as bars 5 and 6, so the progression moves to the subdominant a bar earlier. It is the standard variation in Chicago blues.
Turnaround ending: F7 – F7 – F7 – F7 – A#7 – A#7 – F7 – F7 – C7 – A#7 – C7 – C7. The last four bars — V7, IV7, I7, V7 — are the turnaround. Play the final V7 for a full bar and let it hang before the progression starts again, which is what makes the twelve bars feel like a loop.
The same progression in other keys
The same progression in other keys is 12 bar blues progression in C major, 12 bar blues progression in C# major, 12 bar blues progression in D major, 12 bar blues progression in D# major. The degrees stay the same — I7–I7–I7–I7–IV7–IV7–I7–I7–V7–IV7–I7–V7 — and only the chords change, because each key has its own set of diatonic chords. Learning the 12-bar blues progression in F major as a pattern of degrees, rather than as a list of chord names, is what lets you play it in any key: the pattern is portable, the chords are not. Try the progression in the key a fourth above F major next, then a fifth above, and use the Chord Transposer to move the whole sequence to a new key in one step. The key pages for those keys — for example the key of C major — list the diatonic chords you will need.
Practising the 12-bar blues progression in F major
A good way to practise the 12-bar blues progression in F major is to play it three times in a row without stopping: once slowly, once at a comfortable tempo, and once while humming a simple melody over the top. The melody does not need to be clever — three or four notes from the key of F major are enough — because the point is to hear how the chords support a melody, not to write a song. Then try the progression with a different rhythm: play each chord as an arpeggio instead of a block chord, or strum it with a pattern from the Strumming Pattern Finder and keep time with the Metronome. The sequence is F7 – F7 – F7 – F7 – A#7 – A#7 – F7 – F7 – C7 – A#7 – F7 – C7 and the degrees are I7–I7–I7–I7–IV7–IV7–I7–I7–V7–IV7–I7–V7; once you can play it without looking at the page, you know the 12-bar blues progression in F major.
For a second practice step, take the 12-bar blues progression in F major apart chord by chord. Play the first chord on its own and hold it for two bars, listening to its sound in the key of F major, then add the second chord, then the third, until the whole sequence F7 – F7 – F7 – F7 – A#7 – A#7 – F7 – F7 – C7 – A#7 – F7 – C7 is running. That slow build is the fastest way to learn a progression, because it teaches you the change between each pair of chords rather than the sequence as a blur. When the changes are clean at a slow tempo, raise the tempo a little at a time with the Metronome, and try the progression in the neighbouring keys linked above, where the degrees I7–I7–I7–I7–IV7–IV7–I7–I7–V7–IV7–I7–V7 stay the same and only the chord names change.
