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.

The piano keyboard below contains the notes of the Db 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.
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 Db, Fb, Ab and C.
No. | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
---|---|---|---|---|---|---|---|---|
Note | Db | Eb | Fb | Gb | Ab | Bbb | C | Db |
The second 7th chord below will repeat this, but this time starting on the 2nd note, so its notes will be Eb, Gb, Bbb and Db - 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.
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.

The table below shows the Db 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 Db, Fb, Ab, and C.
No. | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
---|---|---|---|---|---|---|---|
Note | Db | Eb | Fb | Gb | Ab | Bbb | C |
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 Db and Fb 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 Db-min-3rd.
Repeating this for the 5th note / scale degree, the distance between Db and Ab is 7 half-tones, and the note interval name is perfect (P5). More details of this interval are at Db-perf-5th.
Again the 7th note / scale degree, the distance between Db and C is 11 half-tones, and the note interval name is major (M7). More details of this interval are at Db-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, Db, onto this quality, giving us the Db min-maj 7 chord.
The chord symbol i could be followed by the letter a to indicate that it is Db minor-major 7th chord in root position (ie not inverted) - D-flat harmonic minor scale chord ia.
Instead, i could be followed by the letter b to indicate that it is Db minor-major 7th chord in 1st inversion - D-flat harmonic minor scale chord ib.
Letter c could be used to indicate that it is Db minor-major 7th chord in 2nd inversion - D-flat harmonic minor scale chord ic.
Finally, letter d could be used to indicate that it is Db minor-major 7th chord in 3rd inversion - D-flat harmonic minor scale chord id.
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 Db minor-major 7th chord in root position.
For 7th chord inversions, i65 refers to the Db minor-major 7th chord in 1st inversion, i43 refers to the Db minor-major 7th chord in 2nd inversion, and i2 refers to the Db minor-major 7th chord in 3rd inversion.
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, Db, will be moved to the final column of the table.

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 Eb-min-3rd.
Repeating this for the 5th note / scale degree, the distance between Eb and Bbb is 6 half-tones, and the note interval name is diminished (d5). More details of this interval are at Eb-dim-5th.
Again the 7th note / scale degree, the distance between Eb and Db is 10 half-tones, and the note interval name is minor (m7). More details of this interval are at Eb-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, Eb, onto this quality, giving us the Eb half-dim7 chord.
The chord symbol iiø could be followed by the letter a to indicate that it is Eb half-diminished 7th chord in root position (ie not inverted) - D-flat harmonic minor scale chord iiøa.
Instead, iiø could be followed by the letter b to indicate that it is Eb half-diminished 7th chord in 1st inversion - D-flat harmonic minor scale chord iiøb.
Letter c could be used to indicate that it is Eb half-diminished 7th chord in 2nd inversion - D-flat harmonic minor scale chord iiøc.
Finally, letter d could be used to indicate that it is Eb half-diminished 7th chord in 3rd inversion - D-flat harmonic minor scale chord iiød.

So in this key, iiø7 refers to the Eb half-diminished 7th chord in root position.
For 7th chord inversions, iiø65 refers to the Eb half-diminished 7th chord in 1st inversion, iiø43 refers to the Eb half-diminished 7th chord in 2nd inversion, and iiø2 refers to the Eb half-diminished 7th chord in 3rd inversion.
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, Eb, will be moved to the final column of the table.

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, Fb, onto this quality, giving us the Fb aug-maj 7 chord.
The chord symbol III+ could be followed by the letter a to indicate that it is Fb augmented-major 7th chord in root position (ie not inverted) - D-flat harmonic minor scale chord III+a.
Instead, III+ could be followed by the letter b to indicate that it is Fb augmented-major 7th chord in 1st inversion - D-flat harmonic minor scale chord III+b.
Letter c could be used to indicate that it is Fb augmented-major 7th chord in 2nd inversion - D-flat harmonic minor scale chord III+c.

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 C-min-3rd.
Repeating this for the 5th note / scale degree, the distance between C and Gb is 6 half-tones, and the note interval name is diminished (d5). More details of this interval are at C-dim-5th.
Again the 7th note / scale degree, the distance between C and Bbb is 9 half-tones, and the note interval name is diminished (d7). More details of this interval are at C-dim-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 diminished(d7) note intervals is diminished 7th.
And so the complete 7th chord Name prefixes the root note, C, onto this quality, giving us the C dim 7 chord.
The chord symbol viio could be followed by the letter a to indicate that it is C diminished 7th chord in root position (ie not inverted) - D-flat harmonic minor scale chord viioa.
Instead, viio could be followed by the letter b to indicate that it is C diminished 7th chord in 1st inversion - D-flat harmonic minor scale chord viiob.
Letter c could be used to indicate that it is C diminished 7th chord in 2nd inversion - D-flat harmonic minor scale chord viioc.
Finally, letter d could be used to indicate that it is C diminished 7th chord in 3rd inversion - D-flat harmonic minor scale chord viiod.
In place of the a-d symbols above, figured bass symbols could be used to indicate chord positions after viio:
So in this key, viio7 refers to the C diminished 7th chord in root position.
For 7th chord inversions, viio65 refers to the C diminished 7th chord in 1st inversion, viio43 refers to the C diminished 7th chord in 2nd inversion, and viio2 refers to the C diminished 7th chord in 3rd inversion.
This completes the set of all 7th chords that harmonize with the Db harmonic minor scale.
