## 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. A melodic minor scale notes

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

The piano keyboard below contains the notes of the A melodic minor scale.

Starting from the 1st scale 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 scale we are interested in.

#### Identifying the 3 notes in the chord

Triad chords are built using the 1st, 3rdand 5th notes of the scale, so the first triad below will constructed a chord using notes A, C and E.

 No. Note 1 2 3 4 5 6 7 8 A B C D E F# G# A

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

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

#### Identifying the chord quality

Although the above method identifies each triads notes from the scale 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 Scale chord summary for each scale type.

### 3. 1st triad chord in A melodic minor scale

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 A melodic minor scale.

#### Identifying the 3 notes in the chord

The table below shows the A melodic minor scale, 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 A, C, and E.

 No. Note 1 2 3 4 5 6 7 A B C D E 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 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 E is 7 half-tones, and the note interval name is perfect (P5). More details of this interval are at A-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, A, onto this quality, giving us the A minor 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 A minor chord in root position (ie not inverted) - A melodic minor scale chord ia.

Instead, i could be followed by the letter b to indicate that it is A minor chord in 1st inversion - A melodic minor scale chord ib.

Finally, letter c could be used to indicate that it is A minor chord in 2nd inversion - A melodic minor scale 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 A minor chord in 1st inversion, and i64 refers to the A 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 scale note.

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

### 4. 2nd triad chord in A melodic minor scale

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 A melodic minor scale.

#### Identifying the 3 notes in the chord

The table below shows the A melodic minor scale, 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 B, D, and F#.

 No. Note 1 2 3 4 5 6 7 B C D E F# G# A

#### 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 B and D 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 B-min-3rd.

Repeating this for the 5th note / scale degree, the distance between B and F# is 7 half-tones, and the note interval name is perfect (P5). More details of this interval are at B-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, B, onto this quality, giving us the B 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 B minor chord in root position (ie not inverted) - A melodic minor scale chord iia.

Instead, ii could be followed by the letter b to indicate that it is B minor chord in 1st inversion - A melodic minor scale chord iib.

Finally, letter c could be used to indicate that it is B minor chord in 2nd inversion - A melodic minor scale 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 B minor chord in 1st inversion, and ii64 refers to the B 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 scale note.

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

### 5. 3rd triad chord in A melodic minor scale

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 A melodic minor scale.

#### Identifying the 3 notes in the chord

The table below shows the A melodic minor scale, ordered to show the 3rd 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 C, E, and G#.

 No. Note 1 2 3 4 5 6 7 C D E F# G# A B

#### 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 E 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 C-maj-3rd.

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

And so the complete triad chord name prefixes the root note, C, onto this quality, giving us the C augmented 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 C augmented chord in root position (ie not inverted) - A melodic minor scale chord III+a.

Instead, III+ could be followed by the letter b to indicate that it is C augmented chord in 1st inversion - A melodic minor scale chord III+b.

Finally, letter c could be used to indicate that it is C augmented chord in 2nd inversion - A melodic minor scale chord III+c.

#### 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 III+:

So in this key, III+6 refers to the C augmented chord in 1st inversion, and III+64 refers to the C augmented chord in 2nd inversion.

#### The next scale chord

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

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

 No. Note 1 2 3 4 5 6 7 D E F# G# A B C

#### 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 D and F# 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 D-maj-3rd.

Repeating this for the 5th note / scale degree, the distance between D and A is 7 half-tones, and the note interval name is perfect (P5). More details of this interval are at D-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, D, onto this quality, giving us the D 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 D major chord in root position (ie not inverted) - A melodic minor scale chord IVa.

Instead, IV could be followed by the letter b to indicate that it is D major chord in 1st inversion - A melodic minor scale chord IVb.

Finally, letter c could be used to indicate that it is D major chord in 2nd inversion - A melodic minor scale 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 D major chord in 1st inversion, and IV64 refers to the D 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 scale note.

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

 No. Note 1 2 3 4 5 6 7 E F# G# A B C D

#### 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 E 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 E-maj-3rd.

Repeating this for the 5th note / scale degree, the distance between E and B is 7 half-tones, and the note interval name is perfect (P5). More details of this interval are at E-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, E, onto this quality, giving us the E major 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 E major chord in root position (ie not inverted) - A melodic minor scale chord Va.

Instead, V could be followed by the letter b to indicate that it is E major chord in 1st inversion - A melodic minor scale chord Vb.

Finally, letter c could be used to indicate that it is E major chord in 2nd inversion - A melodic minor scale 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 E major chord in 1st inversion, and V64 refers to the E 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 scale note.

This step shows how to identify the notes and the name of a triad chord whose root note is the 6th scale degree of the A melodic minor scale.

#### Identifying the 3 notes in the chord

The table below shows the A melodic minor scale, ordered to show the 6th 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#, A, and C.

 No. Note 1 2 3 4 5 6 7 F# G# A B C D E

#### 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 A 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 6 half-tones, and the note interval name is diminished (d5). More details of this interval are at F#-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, F#, onto this quality, giving us the F# diminished chord.

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

The chord symbol vio could be followed by the letter a to indicate that it is F# diminished chord in root position (ie not inverted) - A melodic minor scale chord vioa.

Instead, vio could be followed by the letter b to indicate that it is F# diminished chord in 1st inversion - A melodic minor scale chord viob.

Finally, letter c could be used to indicate that it is F# diminished chord in 2nd inversion - A melodic minor scale chord vioc.

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 B 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 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 viio could be followed by the letter a to indicate that it is G# diminished chord in root position (ie not inverted) - A melodic minor scale chord viioa.

Instead, viio could be followed by the letter b to indicate that it is G# diminished chord in 1st inversion - A melodic minor scale chord viiob.

Finally, letter c could be used to indicate that it is G# diminished chord in 2nd inversion - A melodic minor scale chord viioc.

#### 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 viio:

So in this key, viio6 refers to the G# diminished chord in 1st inversion, and viio64 refers to the G# diminished chord in 2nd inversion.

This completes the set of all triad chords that harmonize with the A melodic minor scale.
