Developing the ability to identify thirteenth chords by ear is an essential skill for musicians and music students. Thirteenth chords add richness and complexity to music, but their recognition can be challenging without proper training. This article provides ear training exercises aimed at helping you recognize and understand these chords in various songs.
Understanding the Thirteenth Chord
A thirteenth chord is a type of extended chord that includes the root, third, fifth, seventh, ninth, eleventh, and thirteenth notes. In practice, the eleventh is often omitted, and the chord is built on the seventh and thirteenth. Thirteenth chords are commonly used in jazz, funk, and soul music to add depth and color.
Basic Structure of a Thirteenth Chord
- Root
- Major or minor third
- Perfect fifth
- Minor or major seventh
- Ninth (optional)
- Eleventh (often omitted)
- Thirteenth
Understanding the intervallic structure helps in identifying these chords by ear. The thirteenth is an interval of a sixth above the root, which can be challenging to recognize without practice.
Ear Training Exercise 1: Recognizing the Sound of a Thirteenth Chord
Start by listening to recordings of thirteenth chords played on a piano or guitar. Focus on the overall sound and the “color” of the chord. Notice its richness and the way it differs from simpler chords like seventh or ninth chords.
Play a C13 chord and then a C7 chord, and listen carefully to the difference. The C13 will sound more complex and full, with a distinctive “spread” in the upper voices.
Exercise:
- Play a known thirteenth chord (e.g., C13, G13, F13).
- Pause and try to sing the upper extensions (ninth, eleventh, thirteenth).
- Identify the chord by ear in a song that uses extended harmony.
Ear Training Exercise 2: Recognizing Thirteenth Chords in Songs
Find recordings of jazz standards or songs with extended harmonies. Listen for moments where the harmony sounds particularly rich and complex. Use a piano or guitar to test if the chords being played are thirteenth chords.
Try to identify the presence of a thirteenth chord by focusing on the bass line and upper voices. Often, the bass will outline the root, while the upper voices provide the extension notes.
Exercise:
- Listen to jazz recordings with extended chords.
- Identify moments where the harmony sounds especially lush.
- Check if the chords contain the characteristic sixth interval of the thirteenth.
Tips for Effective Ear Training
Consistent practice is key to mastering the recognition of thirteenth chords. Use a variety of songs and recordings to familiarize your ear with different voicings and contexts. Slow down recordings if needed, and isolate the chords to analyze their components.
Keep a journal of your listening exercises, noting which chords are easier or more difficult to identify. Over time, your ability to recognize thirteenth chords will improve significantly.
Conclusion
Identifying thirteenth chords by ear is a valuable skill for musicians interested in jazz, fusion, and complex harmonic textures. Through focused listening and practice, you can train your ear to recognize these chords in various musical contexts, enriching your understanding and performance of extended harmony.
