## Lesson steps

### 1. Piano key note names

This step shows the white and black note names on a piano keyboard so that the note names are familiar for later steps, and to show that the note names start repeating themselves after 12 notes.

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. F-flat locrian mode notes

This step shows the mode note names that will be used to construct all 7th chords that harmonize with those mode notes.

The piano keyboard below contains the notes of the F-flat locrian mode.

Starting from the 1st mode 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 mode 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 mode, so the first 7th chord below will constructed a chord using notes Fb, Abb, Cbb and Ebb.

 No. Note 1 2 3 4 5 6 7 8 Fb Gbb Abb Bbb Cbb Dbb Ebb Fb

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

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

#### Identifying the chord quality

Although the above method identifies each 7th chord notes from the mode 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 Mode chord summary for each mode type.

### 3. 1st 7th chord in F-flat locrian mode

This step shows how to identify the notes and the name of a 7th chord whose root note is the 1st scale degree of the F-flat locrian mode.

#### Identifying the 4 notes in the chord

The table below shows the F-flat locrian mode, 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 Fb, Abb, Cbb, and Ebb.

 No. Note 1 2 3 4 5 6 7 Fb Gbb Abb Bbb Cbb Dbb Ebb

#### 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 Fb and Abb 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 Fb-min-3rd.

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

Again the 7th note / scale degree, the distance between Fb and Ebb is 10 half-tones, and the note interval name is minor (m7). More details of this interval are at Fb-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, Fb, onto this quality, giving us the Fb half-dim7 chord.

#### Scale chord names using a,b and c notation

The chord symbol iø could be followed by the letter a to indicate that it is Fb half-diminished 7th chord in root position (ie not inverted) - F-flat locrian mode chord iøa.

Instead, iø could be followed by the letter b to indicate that it is Fb half-diminished 7th chord in 1st inversion - F-flat locrian mode chord iøb.

Letter c could be used to indicate that it is Fb half-diminished 7th chord in 2nd inversion - F-flat locrian mode chord iøc.

Finally, letter d could be used to indicate that it is Fb half-diminished 7th chord in 3rd inversion - F-flat locrian mode chord iød.

#### 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 iø:

So in this key, iø7 refers to the Fb half-diminished 7th chord in root position.

For 7th chord inversions, iø65 refers to the Fb half-diminished 7th chord in 1st inversion, iø43 refers to the Fb half-diminished 7th chord in 2nd inversion, and iø2 refers to the Fb half-diminished 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 mode note.

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

### 4. 2nd 7th chord in F-flat locrian mode

This step shows how to identify the notes and the name of a 7th chord whose root note is the 2nd scale degree of the F-flat locrian mode.

#### Identifying the 4 notes in the chord

For the 3rd interval (note 2 on the diagram) the distance between Gbb and Bbb 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 Gbb-maj-3rd.

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

Again the 7th note / scale degree, the distance between Gbb and Fb is 11 half-tones, and the note interval name is major (M7). More details of this interval are at Gbb-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), perfect(P5) and major(M7) note intervals is major 7th.

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

#### Scale chord names using a,b and c notation

The chord symbol II could be followed by the letter a to indicate that it is Gbb major 7th chord in root position (ie not inverted) - F-flat locrian mode chord IIa.

Instead, II could be followed by the letter b to indicate that it is Gbb major 7th chord in 1st inversion - F-flat locrian mode chord IIb.

Letter c could be used to indicate that it is Gbb major 7th chord in 2nd inversion - F-flat locrian mode chord IIc.

Finally, letter d could be used to indicate that it is Gbb major 7th chord in 3rd inversion - F-flat locrian mode chord IId.

#### 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:

So in this key, II7 refers to the Gbb major 7th chord in root position.

For 7th chord inversions, II65 refers to the Gbb major 7th chord in 1st inversion, II43 refers to the Gbb major 7th chord in 2nd inversion, and II2 refers to the Gbb 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 mode note.

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

### 5. 3rd 7th chord in F-flat locrian mode

This step shows how to identify the notes and the name of a 7th chord whose root note is the 3rd scale degree of the F-flat locrian mode.

#### Identifying the 4 notes in the chord

The table below shows the F-flat locrian mode, ordered to show the 3rd 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 Abb, Cbb, Ebb, and Gbb.

 No. Note 1 2 3 4 5 6 7 Abb Bbb Cbb Dbb Ebb Fb Gbb

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 Abb-min-3rd.

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

Again the 7th note / scale degree, the distance between Abb and Gbb is 10 half-tones, and the note interval name is minor (m7). More details of this interval are at Abb-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), perfect(P5) and minor(m7) note intervals is minor 7th.

And so the complete 7th chord Name prefixes the root note, Abb, onto this quality, giving us the Abb min 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 Abb minor 7th chord in root position (ie not inverted) - F-flat locrian mode chord iiia.

Instead, iii could be followed by the letter b to indicate that it is Abb minor 7th chord in 1st inversion - F-flat locrian mode chord iiib.

Letter c could be used to indicate that it is Abb minor 7th chord in 2nd inversion - F-flat locrian mode chord iiic.

Finally, letter d could be used to indicate that it is Abb minor 7th chord in 3rd inversion - F-flat locrian mode chord iiid.

This step shows how to identify the notes and the name of a 7th chord whose root note is the 7th scale degree of the F-flat locrian mode.

#### Identifying the 4 notes in the chord

The table below shows the F-flat locrian mode, ordered to show the 7th 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 Ebb, Gbb, Bbb, and Dbb.

 No. Note 1 2 3 4 5 6 7 Ebb Fb Gbb Abb Bbb Cbb Dbb

#### 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 Ebb and Gbb 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 Ebb-min-3rd.

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

Again the 7th note / scale degree, the distance between Ebb and Dbb is 10 half-tones, and the note interval name is minor (m7). More details of this interval are at Ebb-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), perfect(P5) and minor(m7) note intervals is minor 7th.

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

#### Scale chord names using a,b and c notation

The chord symbol vii could be followed by the letter a to indicate that it is Ebb minor 7th chord in root position (ie not inverted) - F-flat locrian mode chord viia.

Instead, vii could be followed by the letter b to indicate that it is Ebb minor 7th chord in 1st inversion - F-flat locrian mode chord viib.

Letter c could be used to indicate that it is Ebb minor 7th chord in 2nd inversion - F-flat locrian mode chord viic.

Finally, letter d could be used to indicate that it is Ebb minor 7th chord in 3rd inversion - F-flat locrian mode chord viid.

#### 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 vii:

So in this key, vii7 refers to the Ebb minor 7th chord in root position.

For 7th chord inversions, vii65 refers to the Ebb minor 7th chord in 1st inversion, vii43 refers to the Ebb minor 7th chord in 2nd inversion, and vii2 refers to the Ebb minor 7th chord in 3rd inversion.

This completes the set of all 7th chords that harmonize with the F-flat locrian mode.
