  • I (1): The tonic chord, the foundation of the key. It represents the home base and creates a sense of resolution.
  • IV (4): The subdominant chord, creating a sense of movement and anticipation. It sets up the dominant chord for a strong resolution.
  • V (5): The dominant chord, building tension and pulling strongly towards the tonic. This chord is often the most "active" in the progression.
  • vi (6): The minor chord built on the sixth degree of the scale, adding a touch of melancholy and color. It offers a contrasting feel to the major tonic chord.

Why It Works

The I-IV-V-vi progression is effective because of the interplay between these chords:
