Examples — Progressions, Melodies, Forms¶

Concrete musical material. Play each on the piano. Don't just read.

1. The four "core pop" progressions¶

In C major (transpose to other keys for practice):

I–V–vi–IV          C  G  Am  F      sweet, anthemic, ubiquitous
vi–IV–I–V          Am F  C   G      emotional, "sad pop"
I–vi–IV–V          C  Am F   G      classic 50s/doo-wop
I–IV–V             C  F  G          rock, blues, simple

Try each with these grooves (right-hand patterns, left hand plays root):

• Whole notes (chord on beat 1).
• Quarter notes (chord on every beat).
• Dotted-quarter / eighth pattern (Coldplay-ish).
• Arpeggio: 1-3-5-3 of each chord (waltz-like).

Same chords, four different songs.

2. The 12-bar blues (in C)¶

| C  | C  | C  | C  |
| F  | F  | C  | C  |
| G  | F  | C  | G  |

Or the dominant-7 version for blues color:

| C7 | F7 | C7 | C7 |
| F7 | F7 | C7 | C7 |
| G7 | F7 | C7 | G7 |

Most blues, R&B, and rock-and-roll songs are this 12-bar template, repeated. Improvise a melody using the C blues scale (C Eb F Gb G Bb) over the entire form.

3. Voice leading: I–IV–V–I with smooth voicings¶

Compare:

Blocky (each chord in root position):

RH:  C-E-G    F-A-C    G-B-D    C-E-G
LH:  C        F        G        C

Smooth (using inversions):

RH:  C-E-G    C-F-A    B-D-G    C-E-G
LH:  C        F        G        C

4. A melody over a 4-chord progression¶

Progression: C – G – Am – F (in C major; whole-note chords; tempo ~80 BPM).

A melody that uses chord tones and stepwise motion:

Measure:    | C       | G       | Am      | F        |
Melody:      E . G . | D . G . | C . E . | F . A .  |
            (eighth-note rests where ".")

Sing it. Now vary the rhythm:

Measure:    | C            | G            | Am           | F            |
Melody:      E─G─G─E─D─    G─G─D─D─B─     C─E─E─C─B─    A─F─F─A─      |

Same notes, different rhythm = different feeling.

5. The major 2-5-1 (jazz cornerstone)¶

In C: ii7 – V7 – I (Dm7 – G7 – Cmaj7).

Voicing example (mid-register):

RH:  F-A-C-E   F-B-D    E-G-B-D
LH:  D         G        C

Notice the smooth voice leading: F stays from Dm7 to G7; A moves down to G; C stays then moves down to B; E moves down to D.

The 2-5-1 is the engine of jazz harmony. Memorize in all 12 keys; it'll appear in thousands of standards.

6. Borrowed chords (modal mixture)¶

Want sudden color in a major-key song? Borrow a chord from the parallel minor.

In C major, parallel minor (C minor) has these chords: i, ii°, III, iv, v, VI, VII = Cm, D°, Eb, Fm, Gm, Ab, Bb.

Most useful borrowings into C major: - iv (Fm) — adds tender melancholy. Try: C – F – Fm – C ("the saddest chord change in pop"). - bVI (Ab) — heroic, Game of Thrones-ish. Try: C – Ab – F – G. - bVII (Bb) — rock/pop driving. Try: F – G – Bb – C ("Sweet Child O' Mine" outro vibe).

These are tools to escape from "this sounds like every other song."

7. Modal vamps for mood¶

Pick a mode; vamp on its tonic chord plus one other diatonic chord; improvise melody using only that mode.

D Dorian (D E F G A B C D, all white keys):

| Dm  | C   | Dm  | C   |

G Mixolydian (G A B C D E F G, all white keys):

| G   | F   | G   | F   |

E Phrygian (E F G A B C D E, all white keys):

| Em  | F   | Em  | F   |

You wrote three completely different songs in 5 minutes by changing the mode.

8. A complete "first song" template¶

Form: Intro - V - C - V - C - B - C - Outro

Key:  G major. Tempo: 90 BPM.

Intro (4 bars):
  | G         | C         | G         | D         |    (instrumental piano)

Verse (8 bars, repeats):
  | G         | C         | Em        | D         |
  | G         | C         | Em        | D         |

  Lyric:      "I see your shadow on my floor" (set syllables to chord-tone melody)

Pre-chorus (4 bars):
  | C         | D         | C         | D         |    (build with rhythm)

Chorus (8 bars, hook here):
  | Em        | C         | G         | D         |
  | Em        | C         | G         | D         |

  Hook:       "And I'll wait for you" (highest melody note on "wait")

Bridge (8 bars):
  | Am        | C         | Em        | G         |
  | Am        | C         | D         | D         |  (last D builds tension)

Outro (4 bars):
  | G         | C         | G         | G         |

This is a writeable template. Pick your own lyric, write a melody to chord tones, and you've finished a song. The first 10 you write will not be brilliant. Write them anyway.

9. A re-harmonization exercise¶

Take the simplest melody you know — "Twinkle Twinkle Little Star":

C  C  G  G  A  A  G   F  F  E  E  D  D  C
"Twin-kle twin-kle lit-tle star  How  I won-der what you are"

Default harmony: C C F C F C G7 C... boring.

Re-harmonize it three ways:

Jazzy (7^th chords + secondary dominants):

Cmaj7  Cmaj7  G7     Cmaj7  Dm7    G7     Cmaj7   |
Bbmaj7 D7sus4 Em7    A7     Dm7    G7     Cmaj7   |

Modal (Dorian-ish):

Cm     Cm     Bb     Cm     Fm     Cm     Bb      |
Fm     Cm     Bb     Cm     Fm     Bb     Cm      |

Cinematic (borrowing from minor and modulating up):

C      Em     Am     C/E    F      Fm     C       |
Eb     Bb/D   C      Am7    Dm7    G7     C       |

The melody hasn't changed; the world it lives in has. This is what re-harmonization power looks like.

10. A daily 30-minute practice plan (working professional)¶

3 min:   warm-up. Hanon exercise or a scale, hands together, 4 keys.
5 min:   sight-reading. New piece, 1–2 grades below comfort, no stopping.
5 min:   ear training app. Intervals + chord quality + scale degrees.
10 min:  theory + chord work. Today: I–vi–IV–V in 6 keys with smooth voicings.
         Tomorrow: V7 → I in all 12 keys.
         Day after: a mode improvisation.
7 min:   composition. Open the latest sketch in MuseScore or a voice memo.
         Add one new bar, one variation, or fix the section that bugs you.

Total: 30 minutes. Five days a week. In a year, you'll have transformed both as a player and as a writer. The plan only fails if you don't actually do it, which is the only thing that matters.
