The Classic and Versatile I-IV-ii-V Chord Progression

The I-IV-ii-V chord progression, also known as the "four-chord progression", is a fundamental and incredibly versatile sequence in music, particularly in popular genres like pop, rock, and blues. It's simple, memorable, and evokes a sense of resolution and satisfaction. Let's delve into the reasons behind its popularity and how you can utilize this powerful progression in your own music.

Understanding the Chords

The four chords are named after their Roman numeral designations in music theory, corresponding to their relationship within a key.

  • I (One) Chord: The tonic chord, representing the root of the key. For example, in the key of C major, the I chord is C major.
  • IV (Four) Chord: The subdominant chord, creating a feeling of movement towards the tonic. In C major, the IV chord is F major.
  • ii (Two) Chord: The minor chord built on the second degree of the scale. In C major, the ii chord is Dm (D minor).
  • V (Five) Chord: The dominant chord, providing a strong sense of resolution and anticipation of the tonic. In C major, the V chord is G major.

Why is it so popular?
