Learning to build and voice thirteenth chords on the piano can greatly enhance your harmonic vocabulary and improvisation skills. These chords add richness and complexity to your playing, making your music more expressive and interesting.
What Are Thirteenth Chords?
Thirteenth chords are extended chords that include the seventh, ninth, eleventh, and thirteenth notes of a scale. They are typically built on the dominant, major, or minor chords and are used to create a lush, full sound.
Basic Structure of a Thirteenth Chord
A basic thirteenth chord contains the following notes:
- Root
- Major or minor third
- Fifth
- Seventh
- Ninth
- Eleventh
- Thirteenth
In practice, not all notes are played at once. Voicing is important to make the chord sound clear and balanced.
Voicing Tips for Beginners
Voicing a thirteenth chord involves selecting which notes to play and how to distribute them across the keyboard. Here are some beginner-friendly tips:
1. Focus on the Root and Thirteenth
Play the root in the bass and the thirteenth in the melody or higher register. This creates a strong harmonic foundation while highlighting the extension.
2. Omitting the Fifth
The fifth is often omitted because it is usually unaltered and does not significantly affect the chord’s quality. Focus on the seventh, ninth, and thirteenth for color.
3. Use Inversions
Inversions help in smooth voice leading and prevent the chord from sounding muddy. For example, play the seventh or ninth in the bass for a different voicing.
Sample Voicings for Common Thirteenth Chords
Here are some practical voicings to try on the piano:
- Dominant 13th: Play G (root), B (major third), F (seventh), A (ninth), E (thirteenth)
- Major 13th: Play C (root), E (major third), B (seventh), D (ninth), A (thirteenth)
- Minor 13th: Play A (root), C (minor third), G (seventh), B (ninth), F (thirteenth)
Experiment with different voicings to find what sounds best for your musical context. Remember, less is often more—omit notes that clutter the sound.
Practice Tips
To master building and voicing thirteenth chords:
- Practice slowly, focusing on accurate note placement.
- Use a metronome to develop consistent timing.
- Try voicing chords in different inversions to improve flexibility.
- Listen carefully to the sound of each voicing and adjust as needed.
- Incorporate these chords into your improvisations and compositions.
With patience and practice, building and voicing thirteenth chords will become a natural part of your piano playing, enriching your harmonic palette and musical expression.
