The 1-3-5 Chord Progression: A Foundation for Piano Harmony
The 1-3-5 chord progression is a fundamental building block in music theory and is often considered the most basic and common progression in western music. It's a simple yet effective tool used in countless songs across various genres. This progression provides a satisfying sense of resolution and is incredibly versatile for creating various musical styles.
Understanding the Basics
The 1-3-5 chord progression refers to playing three chords in a specific order:
- Chord 1 (I): This is the root chord, representing the key of the song. It's a major chord built on the first note of the scale.
- Chord 3 (III): This is the major chord built on the third note of the scale, often referred to as the major third.
- Chord 5 (V): This is the major chord built on the fifth note of the scale, often referred to as the perfect fifth.
Example in C Major:
- Chord 1 (C Major): C-E-G
- Chord 3 (E Major): E-G#-B
- Chord 5 (G Major): G-B-D
Why it Works
The 1-3-5 chord progression works so well because of the relationships between the chords. The 3rd and 5th chords contain notes that resolve harmonically to the root chord. This creates a sense of stability and completion, making the progression sound satisfying and natural.
Playing the Progression
Here's a simple way to play the 1-3-5 progression on the piano:
- Start with the root chord. For C major, place your fingers on C, E, and G.
- Move to the third chord. Shift your hand to E, G#, and B.
- Finish with the fifth chord. Shift your hand again to G, B, and D.
