G harmonic minor 7th chords

The Solution below shows the G harmonic minor scale 7th chords, (i⁷, ii^ø7, III⁺⁷, iv⁷, V⁷, VI⁷, vii^o7) on a piano, with mp3 and midi audio.

The Lesson steps then explain the 7th chord construction from this scale, and how to name the quality of each chord based on note intervals.

For a quick summary of this topic, and to see the chord quality chart for this scale, have a look at Scale chord.

Solution - 7 parts

1. G harmonic minor chord i⁷

The G harmonic minor chord i⁷ is the G min-maj 7 chord, and contains the notes G, Bb, D, and F#.

This tonic 7th chords root / starting note is the 1st note (or scale degree) of the G harmonic minor scale.

The roman numeral for number 1 is 'i', and is used to indicate this is the 1st chord in the scale. Just like a minor chord, the minor-major 7th chord is constructed using a minor third interval, so the roman numeral is shown in lower case.

2. G harmonic minor chord ii^ø7

The G harmonic minor chord ii^ø7 is the A half-dim7 chord, and contains the notes A, C, Eb, and G.

This supertonic 7th chords root / starting note is the 2nd note (or scale degree) of the G harmonic minor scale.

The roman numeral for number 2 is 'ii', and is used to indicate this is the 2nd chord in the scale. Just like a minor chord, the half-diminished 7th chord is constructed using a minor third interval, so the roman numeral is shown in lower case.

The half-diminished symbol '^ø' is placed after the roman numerals to indicate this is a half-diminished 7th chord.

3. G harmonic minor chord III⁺⁷

The G harmonic minor chord III⁺⁷ is the Bb aug-maj 7 chord, and contains the notes Bb, D, F#, and A.

This mediant 7th chords root / starting note is the 3rd note (or scale degree) of the G harmonic minor scale.

The diminished symbol '^o' is placed after the roman numerals to indicate this is a diminished chord.

Lesson steps

1. Piano key note names

The white keys are named using the alphabetic letters A, B, C, D, E, F, and G, which is a pattern that repeats up the piano keyboard.

Every white or black key could have a flat(b) or sharp(#) accidental name, depending on how that note is used. In a later step, if sharp or flat notes are used, the exact accidental names will be chosen.

The audio files below play every note shown on the piano above, so middle C (marked with an orange line at the bottom) is the 2nd note heard.

2. G harmonic minor scale notes

The piano keyboard below contains the notes of the G harmonic minor scale.

Starting from the 1st scale note, each lesson step below will take each note in turn and construct a 7th chord using that note as the root / starting note of that chord.

The 7th chord will be built using only the notes of the scale we are interested in.

Identifying the 4 notes in the chord

7th chords are built using the 1st, 3rd, 5th, and 7th notes of a scale, so the first 7th chord below will constructed a chord using notes G, Bb, D and F#.

The second 7th chord below will repeat this, but this time starting on the 2nd note, so its notes will be A, C, Eb and G - ie. the 1st, 3rd, 5th and 7th positions relative to that 2nd root note.

This pattern is repeated for all 7 notes in the scale, resulting in 7 seventh chords.

Identifying the chord quality

Although the above method identifies each 7th chord notes from the scale used, it does not identify the complete chord name including its quality.

Should each 7th chord that we build be called diminished, half-diminished, minorminor-major, dominant, major, augmented, or augmented-major ?

Every 7th chord must have one of these quality names.

To decide the name the chord quality, each step below will use note intervals to calculate how many half-tones / semitones / piano keys between the root and the 3rd, 5th and 7th notes.).

Taken together, the combination of the 3rd, 5th and 7th note intervals will define the complete 7th chord quality name.

The steps below will show how this works for each 7th chord in turn, but in practice it might just be easier to memorize the triad quality table in the Scale chord summary for each scale type.

3. 1st 7th chord in G harmonic minor scale

Identifying the 4 notes in the chord

The table below shows the G harmonic minor scale, ordered to show the 1st note as the first column in the table.

To identify the 7th chord note names, use the 1st, 3rd, 5th and 7th columns / scale degrees, which are notes G, Bb, D, and F#.

Identifying the chord quality

To identify the 7th chord quality that has these notes, begin by counting the number of half-tones / semitones between the root and each of the notes.

For the 3rd interval (note 2 on the diagram) the distance between G and Bb is 3 half-tones.

Now look at the complete Note interval table, and identify the note interval that has a distance of 3 half-tones (first column), and with an interval no. of 3 (last column).

The note interval name for the 3rd note / scale degree is therefore minor, also called m3 for short. More details of this interval are at G-min-3rd.

Repeating this for the 5th note / scale degree, the distance between G and D is 7 half-tones, and the note interval name is perfect (P5). More details of this interval are at G-perf-5th.

Again the 7th note / scale degree, the distance between G and F# is 11 half-tones, and the note interval name is major (M7). More details of this interval are at G-maj-7th.

Finally, we have the name of the three note intervals of this 7th chord, and can now lookup the name of the 7th chord quality having these intervals.

Looking at the Seventh chord table, the name of the 7th chord quality having minor(m3), perfect(P5) and major(M7) note intervals is minor-major 7th.

And so the complete 7th chord Name prefixes the root note, G, onto this quality, giving us the G min-maj 7 chord.

Scale chord names using a,b and c notation

The chord symbol i could be followed by the letter a to indicate that it is G minor-major 7th chord in root position (ie not inverted) - G harmonic minor scale chord ia.

Instead, i could be followed by the letter b to indicate that it is G minor-major 7th chord in 1st inversion - G harmonic minor scale chord ib.

Letter c could be used to indicate that it is G minor-major 7th chord in 2nd inversion - G harmonic minor scale chord ic.

Finally, letter d could be used to indicate that it is G minor-major 7th chord in 3rd inversion - G harmonic minor scale chord id.

Scale chord names using figured bass notation

In place of the a-d symbols above, figured bass symbols could be used to indicate chord positions after i:

So in this key, i7 refers to the G minor-major 7th chord in root position.

For 7th chord inversions, i65 refers to the G minor-major 7th chord in 1st inversion, i43 refers to the G minor-major 7th chord in 2nd inversion, and i2 refers to the G minor-major 7th chord in 3rd inversion.

The next scale chord

The next step will need to calculate the 7th chord whose root / starting note is next scale note.

To do this, the first column we used in this step, G, will be moved to the final column of the table.

4. 2nd 7th chord in G harmonic minor scale

Identifying the 4 notes in the chord

For the 3rd interval (note 2 on the diagram) the distance between A and C is 3 half-tones.

Now look at the complete Note interval table, and identify the note interval that has a distance of 3 half-tones (first column), and with an interval no. of 3 (last column).

The note interval name for the 3rd note / scale degree is therefore minor, also called m3 for short. More details of this interval are at A-min-3rd.

Repeating this for the 5th note / scale degree, the distance between A and Eb is 6 half-tones, and the note interval name is diminished (d5). More details of this interval are at A-dim-5th.

Again the 7th note / scale degree, the distance between A and G is 10 half-tones, and the note interval name is minor (m7). More details of this interval are at A-min-7th.

Finally, we have the name of the three note intervals of this 7th chord, and can now lookup the name of the 7th chord quality having these intervals.

Looking at the Seventh chord table, the name of the 7th chord quality having minor(m3), diminished(d5) and minor(m7) note intervals is half-diminished 7th.

And so the complete 7th chord Name prefixes the root note, A, onto this quality, giving us the A half-dim7 chord.

Scale chord names using a,b and c notation

The chord symbol ii^ø could be followed by the letter a to indicate that it is A half-diminished 7th chord in root position (ie not inverted) - G harmonic minor scale chord ii^øa.

Instead, ii^ø could be followed by the letter b to indicate that it is A half-diminished 7th chord in 1st inversion - G harmonic minor scale chord ii^øb.

Letter c could be used to indicate that it is A half-diminished 7th chord in 2nd inversion - G harmonic minor scale chord ii^øc.

Finally, letter d could be used to indicate that it is A half-diminished 7th chord in 3rd inversion - G harmonic minor scale chord ii^ød.

Scale chord names using figured bass notation

In place of the a-d symbols above, figured bass symbols could be used to indicate chord positions after ii^ø:

So in this key, ii^ø7 refers to the A half-diminished 7th chord in root position.

For 7th chord inversions, ii^ø65 refers to the A half-diminished 7th chord in 1st inversion, ii^ø43 refers to the A half-diminished 7th chord in 2nd inversion, and ii^ø2 refers to the A half-diminished 7th chord in 3rd inversion.

For the 3rd interval (note 2 on the diagram) the distance between Bb and D is 4 half-tones.

Now look at the complete Note interval table, and identify the note interval that has a distance of 3 half-tones (first column), and with an interval no. of 3 (last column).

The note interval name for the 3rd note / scale degree is therefore major, also called M3 for short. More details of this interval are at Bb-maj-3rd.

Repeating this for the 5th note / scale degree, the distance between Bb and F# is 8 half-tones, and the note interval name is augmented (A5). More details of this interval are at Bb-aug-5th.

Again the 7th note / scale degree, the distance between Bb and A is 11 half-tones, and the note interval name is major (M7). More details of this interval are at Bb-maj-7th.

Finally, we have the name of the three note intervals of this 7th chord, and can now lookup the name of the 7th chord quality having these intervals.

Looking at the Seventh chord table, the name of the 7th chord quality having major(M3), augmented(A5) and major(M7) note intervals is augmented-major 7th.

And so the complete 7th chord Name prefixes the root note, Bb, onto this quality, giving us the Bb aug-maj 7 chord.

Scale chord names using a,b and c notation

The chord symbol III⁺ could be followed by the letter a to indicate that it is Bb augmented-major 7th chord in root position (ie not inverted) - G harmonic minor scale chord III⁺a.

Instead, III⁺ could be followed by the letter b to indicate that it is Bb augmented-major 7th chord in 1st inversion - G harmonic minor scale chord III⁺b.

Letter c could be used to indicate that it is Bb augmented-major 7th chord in 2nd inversion - G harmonic minor scale chord III⁺c.

Finally, letter d could be used to indicate that it is Bb augmented-major 7th chord in 3rd inversion - G harmonic minor scale chord III⁺d.

Scale chord names using figured bass notation

In place of the a-d symbols above, figured bass symbols could be used to indicate chord positions after III⁺:

So in this key, III⁺7 refers to the Bb augmented-major 7th chord in root position.

For 7th chord inversions, III⁺65 refers to the Bb augmented-major 7th chord in 1st inversion, III⁺43 refers to the Bb augmented-major 7th chord in 2nd inversion, and III⁺2 refers to the Bb augmented-major 7th chord in 3rd inversion.
