Advanced Chord Progressions
Move beyond diatonic harmony without losing musical direction.
A practical guide to secondary dominants, borrowed chords, inversions, chromatic harmony, extensions and voice-leading—for pianists, composers and theory students ready for the next layer.

Starting Point
Complexity is not the goal. Control is.
Advanced harmony begins when you can change colour, tension and direction deliberately—not when you simply add more chord symbols.
1 · Harmonic Function
Know what each chord is doing before you make it richer.
A progression becomes easier to control when you can hear broad tonic, predominant and dominant behaviour underneath the surface colour.
In C major, C is the clearest tonic. Dm and F often prepare movement away from tonic. G and B diminished create dominant pressure back toward C. Advanced devices work best when they intensify, delay or recolour one of those basic functions rather than obscure it.
Core Devices
Five ways to make a progression more expressive.
Use one device at a time until you can hear what it contributes.
Temporarily intensify another chord.
In C major, A7 can point strongly to Dm because A7 is the dominant of D. D7 can point to G. These chords introduce chromatic notes, but their destinations remain clear.
Borrow colour from the parallel mode.
In C major, Fm, A♭ and B♭ can be borrowed from C minor. The borrowed iv chord is especially expressive because A♭ often falls by semitone to G.
Design the bass line as carefully as the chord sequence.
Root-position harmony can sound block-like. Inversions and slash chords let the bass move by step, preserve common tones and create smoother inner motion.
Add colour without changing the harmonic job.
Cmaj9 can still function as tonic. Dm9 can still behave as predominant. G13 can still function as dominant. The colour changes while the direction remains understandable.
Use tension as a bridge between stable chords.
Diminished and semitone approach chords can create momentum when their voices resolve clearly. The listener should still be able to hear the destination.
Shift colour dramatically by third.
Chromatic mediants can transform the harmonic landscape while preserving common tones. They are particularly effective in film, Romantic and contemporary writing when used with restraint.
Progressions to Analyse
Hear the technique inside the chord sequence.
These examples are not recipes to memorise. They show how different devices create direction, colour and release.
A7 acts as V/ii, intensifying the move to Dm7. G13 keeps dominant function while adding colour before the return to tonic.
E7 is V/vi. Fm is borrowed iv from C minor. One progression combines chromatic function with modal colour.
A chain of applied dominants creates continuing forward pressure while every chromatic chord retains a clear destination.
Borrowed iv, inversion and secondary dominant combine with familiar ii–V–I motion.
Borrowed ♭VI and iv darken the colour before the dominant restores a strong pull back to C.
Build It Deliberately
Change one harmonic variable at a time.
The safest way to write richer harmony is to begin with a progression that already works, then refine it in stages.
- 1
Write the diatonic version.
Make sure the basic progression already has direction and a convincing arrival.
- 2
Strengthen one destination.
Add a secondary dominant before a chord you want to emphasise.
- 3
Add one borrowed colour.
Try iv, ♭VI or ♭VII where the musical style supports it.
- 4
Improve the bass and inner voices.
Use inversions, common tones and semitone movement to make the progression connect.
- 5
Add extensions last.
Use sevenths, ninths or thirteenths only after the underlying progression already works.
Common Problems
What makes advanced harmony sound less convincing.
Too many devices at once
If every chord is chromatic, extended and inverted, the listener may lose the sense of direction. Let one colour be heard before adding another.
Ignoring the bass line
A sophisticated chord symbol does not compensate for awkward bass movement. Strong bass design can make simple harmony sound more mature.
Changing every voice
Hold common tones and look for semitone movement. Smooth inner parts often create more sophistication than extra chord extensions.
Using chromatic chords without resolution
Colour becomes noise when the listener cannot hear what the tension is doing. Advanced harmony still benefits from expectation and release.
