Introduction to Major and Minor 10th Chords

Chords are the building blocks of music, and understanding their structure can greatly enhance your harmonic palette. In this article, we explore the unique characteristics of major 10th and minor 10th chords, their origins, and how to use them effectively.

The Structure and Notes of Major and Minor 10th Chords

A 10th chord is an extended chord, meaning it includes notes beyond the basic triad (1, 3, 5). Specifically, a 10th chord includes the root, a 10th above the root, and the perfect 5th above the root. Here’s a breakdown of the structure and notes for both major and minor 10th chords:

Major 10th Chord

Structure: Root, major 3rd, perfect 5th, major 10th
Notes: C major example

Root: C Major 3rd: E Perfect 5th: G Major 10th: B (an octave plus a third above the root)

Notes in C Major 10th: C, E, G, B

Minor 10th Chord

Structure: Root, minor 3rd, perfect 5th, minor 10th
Notes: C minor example

Root: C Minor 3rd: Eb Perfect 5th: G Minor 10th: Bb (an octave plus a third below the root)

Notes in C Minor 10th: C, Eb, G, Bb

Historical and Contextual Usage

These chords may seem novel, but they have a rich history in music. For instance, Christopher Smith notes that a 10th chord is a chord that combines the major and minor 3rds with the same root. Often, the major 3rd is in a lower octave and the minor 3rd in a higher one, creating an 10th interval. Less frequently, the minor 3rd is combined with the major 10th, as in Bartok and Mingus compositions.

Analysis and Perception

From a theoretical standpoint, the 10th chord is part of the dominant chord family. However, many musicians prefer to use the term b10 (flat 10) instead of 9th, which is just a preference. This chord represents a tension note, as it introduces a minor quality into a major or dominant chord, thereby enriching the harmonic landscape. Musicians often find creative ways to incorporate these chords into their music, expanding their harmonic palette.

Conclusion

Understanding and using major 10th and minor 10th chords can significantly enhance your musical vocabulary. These chords offer a wealth of harmonic possibilities and can add a unique depth to your compositions. Whether you are a seasoned musician or just starting out, exploring these chords can be a rewarding experience.
