Extended chords are an essential part of jazz, pop, and classical piano music. They add richness and complexity to your playing by incorporating notes beyond the basic triads. Understanding how to build and use 9ths, 11ths, and 13ths can greatly enhance your musical expression.
What Are Extended Chords?
Extended chords are chords that include notes beyond the seventh. These notes are called extensions and are added to the basic triad and seventh chords. The most common extensions are the 9th, 11th, and 13th.
Building Extended Chords
To build an extended chord, start with a basic chord and add the appropriate extension. For example, a C major 9th chord includes the notes of a C major triad (C, E, G), plus the 7th (B), and the 9th (D). The general formula for these chords is:
- Root
- Major or minor third
- Perfect fifth
- Minor or major seventh
- Extended note (9th, 11th, or 13th)
Each extension adds a different color to the chord. The 9th adds a smooth, jazzy sound; the 11th creates a more airy feel; and the 13th provides a rich, full sound.
Examples of Extended Chords
Here are some common extended chords:
- Cmaj9: C – E – G – B – D
- C11: C – E – G – Bb – D – F
- C13: C – E – G – Bb – D – A
Using Extended Chords in Playing
Extended chords are often used in jazz and popular music to add color and sophistication. When playing, consider voice leading—smoothly moving from one chord to another. You can also omit certain notes, like the fifth, to make the chords easier to play.
Experiment with different voicings and inversions to find the sound that best fits your style. Remember, the goal is to enhance your music without overcomplicating it.
Conclusion
Understanding and incorporating extended chords like 9ths, 11ths, and 13ths can elevate your piano playing. With practice, you’ll be able to add more emotional depth and complexity to your performances. Keep exploring these chords to discover new musical possibilities!
