    What are Major 7th Chords?

    A major seventh chord is a type of chord that consists of a major triad with an additional major seventh interval. It can be found as “maj7,” “M7,” or “Δ”. Maj7 chords have a lush and dreamy sound and can be used as substitutes for tonic and subdominant chords in major keys.

     


    Building the G# Maj7 Chord: Different Approaches

     

    Starting from the G# Major Scale:

    To build a major 7th chord, you can use the major scale as a reference. You will need to combine a Root, a major 3rd, a 5th interval, and a major 7th.

    For instance, to build the G# Maj7 chord, you can start with the G# Major scale, which consists of G#, A#, B#, C#, D#, E#, and Fx.

    To form a G# Maj7 chord, use the formula R, 3, 5, 7 as follows:

    1. Start with the Root note, G#.
    2. Choose the major 3rd interval, B#.
    3. Add the 5th interval, which is D#.
    4. Lastly, include the major 7th interval, Fx (which is equivalent to a natural G but we’ll call it “F-double-sharp” to preserve the basic interval structure of the chord).

    By using this straightforward formula, you can produce a major 7th chord from any major scale.

     


    by Combining Intervals:

    One method to create a major 7th chord is by combining specific intervals – a major 3rd, a minor 3rd, and again a major 3rd. To illustrate, let’s use the G# Maj7 chord as an example.

    3 + m3 + 3 = Major 7th Chords

    By examining the intervals between the notes, we can see that G#-B# forms a major 3rd interval, B#-D# creates a minor 3rd interval, and D#-G is also a major 3rd. These three intervals can be stacked together to create the G# Maj7 chord.

     


    How to Use G# Maj7 in a Chord Progression

     

    These tables display the harmonized major and natural minor scales where you can find a G# Maj7 chord.

    In the context of major scales, the G# Maj7 chord functions as the tonic chord (I) in the key of G#. Additionally, it can also be used as the subdominant chord in the D# major scale.

    In natural minor scales, the G# Maj7 chord assumes different roles. It acts as the mediant chord in the E# natural minor scale and as the submediant chord in the B# natural minor scale.

    It’s important to keep in mind that all these keys are considered theoretical and not commonly used in practice. This is mainly due to their complex nature, with a high number of accidentals. It’s more convenient to refer to their enharmonic equivalent keys, as they involve fewer accidentals.
