Blues Forms, Dominant Color and Turnarounds

Blues harmony behaves differently from ordinary major-key functional harmony. Dominant sevenths can appear on I, IV and V without sounding like temporary key changes, and the form often matters as much as the chord list. The generator keeps longer blues forms intact instead of reducing everything to a four-chord loop.

I7 – I7 – I7 – I7 | IV7 – IV7 – I7 – I7 | V7 – IV7 – I7 – V7G7 – G7 – G7 – G7 | C7 – C7 – G7 – G7 | D7 – C7 – G7 – D7

A standard 12-bar framework with a V7 turnaround in the final bar to drive another chorus.

I7 – IV7 – I7 – V7G7 – C7 – G7 – D7

A compact blues skeleton useful when you want the dominant-seventh language without committing to a complete 12-bar phrase.

i7 – iv7 – i7 – V7Gm7 – Cm7 – Gm7 – D7 in G minor

A minor-blues direction: the major V7 adds a stronger cadence while the i and iv keep the darker center.

Blues is as much form as progression

Repeating I7 for several bars is not wasted space; it establishes the form and gives the melody, riff and groove room to develop. The movement to IV7 and V7 becomes meaningful because the listener has spent time hearing the tonic area first.

Mixolydian explains part of the sound, especially the flat seventh over a major tonic, but blues vocabulary is not limited to one strict scale. Chromatic melody notes, dominant sevenths and minor/major inflection are all part of the language.
