Introduction
Music theory often sounds intimidating—but one of the most powerful progressions you’ll ever need to know is I–IV–V. Whether you’re playing rock, blues, pop, or even Indian film music, this simple 3-chord combo is everywhere.
In this blog, we’ll:
- Break down what the I–IV–V progression is
- Explore how it appears in different genres
- Show you real song examples (including A.R. Rahman!)
What is the I–IV–V Progression?
In any major scale, the I, IV, and V chords are built on the 1st, 4th, and 5th scale degrees. For example, in C Major:
- I = C major
- IV = F major
- V = G major
These chords create tension and release, one of the most important storytelling tools in music.
1. Rock & Roll / Blues
The I–IV–V is the backbone of 12-bar blues and early rock.
Example:
- Johnny B. Goode – Chuck Berry (I–IV–V in Bb Major)
- Hound Dog – Elvis Presley
How it’s used:
Simple, repetitive, high-energy progressions with expressive soloing on top.
2. Pop
Many pop songs use I–IV–V either on its own or as part of a bigger loop.
Example:
- Twist and Shout – The Beatles (D–G–A)
- La Bamba – Ritchie Valens (C–F–G)
Why it works:
It’s singable, predictable, and hooks listeners fast.
3. Indian Film Music (ARR & Others)
While Indian film composers often use complex ragas, the I–IV–V structure sneaks in, especially in Western-influenced or fusion arrangements.
Examples:
- Ennavale Adi Ennavale (Key of F: F–Bb–C at 1:25 in the interlude) – A.R. Rahman

- Pee Loon (I–IV–V is used in C major as C–F–G during verses) – Pritam

Used to create triumphant, powerful emotional surges while still staying accessible.
4. Classical Crossover & Gospel
Used to build uplifting or devotional moods.
Example:
- Amazing Grace (C–F–G)
- Gospel choir arrangements frequently emphasize I–IV–V for emotional release
Play It Yourself: Exercise
Try this progression in 3 keys:
