IIVVIProgression

IIVVIProgression is a term used in music theory discussions to denote a specific five-chord progression with the sequence I, I, V, V, I in a given key. The label combines the roman numeral initials with the word progression to describe a cadential pattern that emphasizes tonic repetition and a strong cadence.

Harmonic function: The first two I chords extend the tonic area, creating a stable start. The subsequent V, V introduces dominant tension, and the final I resolves the tension with a conclusive cadence. The progression is often treated as a compact cadence formula or looping motif in tonal music.

Variations and transpositions: The IIVVIProgression can be transposed to any key. It may occur with major triads or be colored with sevenths (I7, V7). Composers sometimes embellish the basic pattern with passing chords or substitute the second I or V with related chords to alter color while preserving function.

Usage: The progression appears in pop, rock, and film scoring as an intro, turnaround, or motif that reinforces a sense of return to the tonic. In C major, the pattern would typically be C–C–G–G–C, with rhythm and articulation shaping its character.

Origin and reception: The exact term IIVVIProgression is not a standard entry in formal music theory, but it is used in online teaching materials and discussions to name this simple, repetitive cadential pattern. As such, it is best viewed as a descriptive label for a commonly encountered cadence device rather than a formal theoretical category.
