G#mMaj7 Piano Chord

Piano Diagram of G#mMaj7 in Root Position

The G#mMaj7 chord is a minor chord rooted in the key of G#, consisting of the notes G#, B, D#, and F_x. The main feature of this chord is the inclusion of a major 7th interval on a minor chord. Additionally, the presence of an augmented fifth between the minor 3rd and major 7th creates a sense of dissonance. In this article, we will delve into the music theory of the G#mMaj7 chord and its role within chord progressions.

Building the G#mMaj7 Chord: Different Approaches

Starting from the G# Major Scale

A G# minor major 7th chord is formed by taking the root note G#, adding a minor 3rd interval (B), a perfect 5th interval (D#), and finally a major 7th interval F_x (G). Although these intervals are typically derived from a minor scale, for educational purposes, it is often more intuitive to explain their construction using a major scale.

For example, to build a G#mMaj7 chord, you can start with the G# Major scale:

 

 

 

To create a G#mMaj7 chord, apply the formula R, m3, 5, 7 in the following manner:

1. Begin with the Root note, which is G#.
2. Select the minor 3rd interval, B.
3. Include the 5th note, D#.
4. Finally, add the major 7th interval F_x (G), which is the 7th note of the scale.

By following this simple formula, you can create a minor major 7th chord from any major scale.

by Combining Intervals

Another way to form a minor major 7th chord is by combining specific intervals – a minor 3rd, a major 3rd, and another major 3rd.

m3 + 3 + 3 = minor Major 7th chords

If we observe the intervals between the notes, we can notice that:

• G#-B creates a minor 3rd interval,
• B-D# forms a major 3rd interval,
• and D#-F_x is another major 3rd interval.

By stacking these three intervals together, we can build the G#mMaj7 chord.

How to Use G#mMaj7 in a Chord Progression

 

The G#mMaj7 chord is characterized by the presence of a major 7th interval, which is not found in either the natural minor or major scales. It’s diatonic in other scales like the harmonic and melodic minor scale, which features a minor major seventh chord on their first degree.

Typically, the G#mMaj7 chord is used as a passing chord, temporarily transitioning towards a more stable G#m7. Additionally, it can serve as an ending chord in specific musical contexts. This is because the chord produces a mysterious and intriguing atmosphere, making it suitable for certain musical styles and compositions.

Non-diatonic positions in Natural minor and Major Scales

The major seventh interval of the G#mMaj7 chord, which is F_x, clashes with the F# note present in both natural minor and major scales. For this reason, the G#mMaj7 chord is not commonly used as a standalone chord (except in endings).

The G#mMaj7 chord is used:

• on the first and fourth degree of minor scales or
• on the second and on the sixth degree of major scales,
• as part of a chromatic progression towards a minor 7th chord.
• While less common, it can still be used on the fifth degree of both minor and major scales.

Here are the tables of the major and natural minor scales that include the G# minor 7th, which can be complemented by a G#mMaj7 chord.

 

on Natural minor Scales

Non-diatonic passing chord to the:

• Tonic chord in G# minor
• Subdominant chord in D# minor
• Dominant chord in C# minor (less common)

 

on Major Scales

Non-diatonic passing chord to the:

• Supertonic chord in F# Major
• Mediant chord in E Major
• Submediant chord in B Major

G#mMaj7 Function in Major and minor Keys

The chord G#mMaj7 does not serve a functional role in harmonic progressions within major and minor keys as it is not diatonic. Rather, it should be considered as a color to add in certain contexts where modulation to a G#m7 chord is feasible or appropriate.

G#mMaj7 as Passing Chord in G# minor

In the key of G# minor, the G#mMaj7 serves as a passing chord to the Tonic chord, G#m7. The chord’s major 7th note, F_x, clashes with the F# note found in the G# minor scale, creating a tension that needs to be resolved. This can be achieved by transitioning the chord to a more stable G#m7 chord, which typically occurs within the same measure as the G#mMaj7 chord.

Alternatively, the G#mMaj7 chord can be left alone as an ending chord, but it’s too dissonant to be played for a whole measure within a chord progression.

Conclusion

The chord progressions and examples presented in this post provide a comprehensive overview of the most common uses of the G#mMaj7 chord. It’s important to note, however, that there are many advanced harmony-related topics that could not be included due to space constraints. These topics include chord progressions built on harmonic and melodic scales, modal scales, hidden tonality, secondary dominants and other chord substitutions, non-functional harmony and atonal music, modal interchange and borrowed chords, voice leading and counterpoint, chromatisms, jazz harmony…I mean, music theory is a huge topic!

Although I couldn’t cover all of these topics in my post, I encourage readers to continue exploring these areas in their own study and research. By expanding your knowledge in these advanced areas of music theory, you can gain a deeper understanding of the harmonic possibilities that exist beyond the basics presented here.
