I-ii-V-I progression

Definition

The I-ii-V-I progression is a common chord progression in music theory that consists of the tonic (I), supertonic (ii), dominant (V), and back to the tonic (I) chords. It is often used in various genres of music to create a sense of resolution and musical tension.

Analogy

Think of the I-ii-V-I progression as a journey from home to a faraway place and then back home again. Just like going on an adventure, the chords take you away from the starting point (tonic) and then guide you back for a satisfying conclusion.

Tonic: The tonic chord is the first scale degree or "home" chord in a key. It provides stability and serves as a reference point for other chords.

Supertonic: The supertonic chord is built on the second scale degree. It adds some tension but still maintains a sense of connection with the tonic.

Dominant: The dominant chord is built on the fifth scale degree. It creates strong tension and leads back to the tonic, providing resolution.
