## 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. E-flat mixolydian mode notes

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

The piano keyboard below contains the notes of the E-flat mixolydian mode.

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

The triad chord will be built using only the notes of the mode we are interested in.

#### Identifying the 3 notes in the chord

Triad chords are built using the 1st, 3rdand 5th notes of the mode, so the first triad below will constructed a chord using notes Eb, G and Bb.

 No. Note 1 2 3 4 5 6 7 8 Eb F G Ab Bb C Db Eb

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

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

#### Identifying the chord quality

Although the above method identifies each triads notes from the mode used - it does not identify the complete chord name including its quality.

Should each triad that we build be called major, minor, augmented, or diminished ? Every triad 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 (and 5th).

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

The steps below will show how this works for each triad 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 triad chord in E-flat mixolydian mode

This step shows how to identify the notes and the name of a triad chord whose root note is the 1st scale degree of the E-flat mixolydian mode.

#### Identifying the 3 notes in the chord

The table below shows the E-flat mixolydian mode, ordered to show the 1st note as the first column in the table.

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

 No. Note 1 2 3 4 5 6 7 Eb F G Ab Bb C Db

#### Identifying the chord quality

To identify the triad 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 Eb and G 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 Eb-maj-3rd.

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

Finally, we have the name of the two note intervals of this triad, and can now lookup the name of the triad chord quality having these intervals.

Looking at the Triad chord table, the name of the triad chord quality having major(M3) and perfect(P5) note intervals is major.

And so the complete triad chord name prefixes the root note, Eb, onto this quality, giving us the Eb major 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 Eb major chord in root position (ie not inverted) - E-flat mixolydian mode chord Ia.

Instead, I could be followed by the letter b to indicate that it is Eb major chord in 1st inversion - E-flat mixolydian mode chord Ib.

Finally, letter c could be used to indicate that it is Eb major chord in 2nd inversion - E-flat mixolydian mode chord Ic.

#### Scale chord names using figured bass notation

In place of the b or c symbols above, figured bass symbols could be used to indicate inversions after the chord number symbols I:

So in this key, I6 refers to the Eb major chord in 1st inversion, and I64 refers to the Eb major chord in 2nd inversion.

#### The next scale chord

The next step will need to calculate the triad chord whose root / starting note is next mode note.

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

### 4. 2nd triad chord in E-flat mixolydian mode

This step shows how to identify the notes and the name of a triad chord whose root note is the 2nd scale degree of the E-flat mixolydian mode.

#### Identifying the 3 notes in the chord

The table below shows the E-flat mixolydian mode, ordered to show the 2nd note as the first column in the table.

To identify the triad chord note names, use the 1st, 3rd, and 5th columns / scale degrees, which are notes F, Ab, and C.

 No. Note 1 2 3 4 5 6 7 F G Ab Bb C Db Eb

#### Identifying the chord quality

To identify the triad 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 F and Ab 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 F-min-3rd.

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

Finally, we have the name of the two note intervals of this triad, and can now lookup the name of the triad chord quality having these intervals.

Looking at the Triad chord table, the name of the triad chord quality having minor(m3) and perfect(P5) note intervals is minor.

And so the complete triad chord name prefixes the root note, F, onto this quality, giving us the F minor 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 F minor chord in root position (ie not inverted) - E-flat mixolydian mode chord iia.

Instead, ii could be followed by the letter b to indicate that it is F minor chord in 1st inversion - E-flat mixolydian mode chord iib.

Finally, letter c could be used to indicate that it is F minor chord in 2nd inversion - E-flat mixolydian mode chord iic.

#### Scale chord names using figured bass notation

In place of the b or c symbols above, figured bass symbols could be used to indicate inversions after the chord number symbols ii:

So in this key, ii6 refers to the F minor chord in 1st inversion, and ii64 refers to the F minor chord in 2nd inversion.

#### The next scale chord

The next step will need to calculate the triad chord whose root / starting note is next mode note.

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

### 5. 3rd triad chord in E-flat mixolydian mode

This step shows how to identify the notes and the name of a triad chord whose root note is the 3rd scale degree of the E-flat mixolydian mode.

#### Identifying the 3 notes in the chord

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

 No. Note 1 2 3 4 5 6 7 G Ab Bb C Db Eb F

#### Identifying the chord quality

To identify the triad 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 Db is 6 half-tones, and the note interval name is diminished (d5). More details of this interval are at G-dim-5th.

Finally, we have the name of the two note intervals of this triad, and can now lookup the name of the triad chord quality having these intervals.

Looking at the Triad chord table, the name of the triad chord quality having minor(m3) and diminished(d5) note intervals is diminished.

And so the complete triad chord name prefixes the root note, G, onto this quality, giving us the G diminished chord.

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

The chord symbol iiio could be followed by the letter a to indicate that it is G diminished chord in root position (ie not inverted) - E-flat mixolydian mode chord iiioa.

Instead, iiio could be followed by the letter b to indicate that it is G diminished chord in 1st inversion - E-flat mixolydian mode chord iiiob.

Finally, letter c could be used to indicate that it is G diminished chord in 2nd inversion - E-flat mixolydian mode chord iiioc.

#### Scale chord names using figured bass notation

In place of the b or c symbols above, figured bass symbols could be used to indicate inversions after the chord number symbols iiio:

So in this key, iiio6 refers to the G diminished chord in 1st inversion, and iiio64 refers to the G diminished chord in 2nd inversion.

#### The next scale chord

The next step will need to calculate the triad chord whose root / starting note is next mode note.

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

### 6. 4th triad chord in E-flat mixolydian mode

 No. Note 1 2 3 4 5 6 7 Ab Bb C Db Eb F G

#### Identifying the chord quality

To identify the triad 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 Ab and C 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 Ab-maj-3rd.

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

Finally, we have the name of the two note intervals of this triad, and can now lookup the name of the triad chord quality having these intervals.

Looking at the Triad chord table, the name of the triad chord quality having major(M3) and perfect(P5) note intervals is major.

And so the complete triad chord name prefixes the root note, Ab, onto this quality, giving us the Ab major chord.

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

The chord symbol IV could be followed by the letter a to indicate that it is Ab major chord in root position (ie not inverted) - E-flat mixolydian mode chord IVa.

Instead, IV could be followed by the letter b to indicate that it is Ab major chord in 1st inversion - E-flat mixolydian mode chord IVb.

Finally, letter c could be used to indicate that it is Ab major chord in 2nd inversion - E-flat mixolydian mode chord IVc.

#### Scale chord names using figured bass notation

In place of the b or c symbols above, figured bass symbols could be used to indicate inversions after the chord number symbols IV:

So in this key, IV6 refers to the Ab major chord in 1st inversion, and IV64 refers to the Ab major chord in 2nd inversion.

#### The next scale chord

The next step will need to calculate the triad chord whose root / starting note is next mode note.

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

For the 3rd Interval (note 2 on the diagram) the distance between Bb and Db 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 Bb-min-3rd.

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

Finally, we have the name of the two note intervals of this triad, and can now lookup the name of the triad chord quality having these intervals.

Looking at the Triad chord table, the name of the triad chord quality having minor(m3) and perfect(P5) note intervals is minor.

And so the complete triad chord name prefixes the root note, Bb, onto this quality, giving us the Bb minor chord.

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

The chord symbol v could be followed by the letter a to indicate that it is Bb minor chord in root position (ie not inverted) - E-flat mixolydian mode chord va.

Instead, v could be followed by the letter b to indicate that it is Bb minor chord in 1st inversion - E-flat mixolydian mode chord vb.

Finally, letter c could be used to indicate that it is Bb minor chord in 2nd inversion - E-flat mixolydian mode chord vc.

#### Scale chord names using figured bass notation

In place of the b or c symbols above, figured bass symbols could be used to indicate inversions after the chord number symbols v:

So in this key, v6 refers to the Bb minor chord in 1st inversion, and v64 refers to the Bb minor chord in 2nd inversion.

#### The next scale chord

The next step will need to calculate the triad chord whose root / starting note is next mode note.

 No. Note 1 2 3 4 5 6 7 C Db Eb F G Ab Bb

#### Identifying the chord quality

To identify the triad 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 C and Eb 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 C-min-3rd.

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

Finally, we have the name of the two note intervals of this triad, and can now lookup the name of the triad chord quality having these intervals.

Looking at the Triad chord table, the name of the triad chord quality having minor(m3) and perfect(P5) note intervals is minor.

And so the complete triad chord name prefixes the root note, C, onto this quality, giving us the C minor chord.

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

The chord symbol vi could be followed by the letter a to indicate that it is C minor chord in root position (ie not inverted) - E-flat mixolydian mode chord via.

Instead, vi could be followed by the letter b to indicate that it is C minor chord in 1st inversion - E-flat mixolydian mode chord vib.

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 Db-maj-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.

Finally, we have the name of the two note intervals of this triad, and can now lookup the name of the triad chord quality having these intervals.

Looking at the Triad chord table, the name of the triad chord quality having major(M3) and perfect(P5) note intervals is major.

And so the complete triad chord name prefixes the root note, Db, onto this quality, giving us the Db major 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 Db major chord in root position (ie not inverted) - E-flat mixolydian mode chord VIIa.

Instead, VII could be followed by the letter b to indicate that it is Db major chord in 1st inversion - E-flat mixolydian mode chord VIIb.
