Adding a B9 to a Maj7 Chord in Jazz: A Comprehensive Guide

Are additions like a B9 to a Maj7 chord allowed in jazz?

Flexibility in Jazz Harmony

Yes, you can add modifications like a B9 to a Maj7 chord in jazz. In fact, there are two general perspectives to consider. The first is that you can experiment with any alterations that serve your harmonic and sonic goals. There are no steadfast rules. The second perspective is that altering a Maj7 chord to include a B9 is a common and harmonically rich move. Itrsquo;s worth exploring to discover its unique qualities.

Traditional Usage and Practical Application

Traditionally, altered notes such as the b9 are more commonly added to a dominant 7th chord, like a G7b9 in the key of C. This creates an interesting minor 3rd interval with the b7, adding a unique flavor. In jazz, you might skip the root of the dominant 7th chord and form a diminished 7th chord by removing the root. For instance, removing G from G7b9 would result in a Gdim7 chord.

Though adding a B9 to a Maj7 chord can sound dissonant, especially if yoursquo;re not used to hearing this sound in mainstream music, it can be incredibly expressive and dynamic. If you decide to use it, the key is understanding where to lead the dissonance. The most crucial decision is how the chord will resolve or what chord follows and precedes it.

Evaluating the B9 in the Chord

The B9 will create a major second interval with the major 7th of the Maj7 chord, which is less consonant but can add a specific tension. Experimenting with intervals and voicings can help you achieve a desired musical effect. Itrsquo;s also useful to analyze how the B9 interacts with each chord tone within the chord for a richer understanding.
