Piano Ballad Accompaniment: Block Chords, Broken Chords and Arpeggios (Creep Progression)
To accompany a ballad on piano, play the I–III–IV–iv progression (G–B–C–Cm in G major) with smooth inversions in the right hand as block chords, broken chords or 16th-note arpeggios, while the left hand plays root octaves as whole notes, minims, toggles or soft ghost-note eighths.
Key points
- The Creep-style ballad progression is I – III – IV – iv, e.g. G – B – C – Cm in G major.
- Keep common notes in place and slide shapes to make chord changes smooth.
- Right hand: block chords, broken chords (top two then bottom) and 16th-note arpeggios (high, low, middle, low).
- Left hand builds from whole-note octaves to minims, root–octave toggles and disco eights.
- For a true ballad feel, hold the root every two beats with the pinky and play soft thumb ghost notes in eighths.
What this lesson teaches
This is part one of a three-part series by Jason Zac on ballad-style piano accompaniment, the kind you play while a singer, duo or choir carries the melody. You learn one chord progression, three right-hand patterns and a set of left-hand rhythm patterns that build from very simple to quite expressive. It suits beginners who know their basic triads and want to sound like a real accompanist.
The chord progression
The progression is inspired by Radiohead's Creep and appears in many melancholic ballads. In Roman numerals it is I – III – IV – iv. It is slightly non-diatonic: the III chord is major (in a major key it is normally minor), and the iv chord is borrowed minor. The move from IV to iv is a minor plagal sound that pulls nicely back to I.
- G major: G (G B D) – B (B D# F#) – C (C E G) – Cm (C Eb G)
- F major: F – A (A C# E) – Bb (Bb D F) – Bbm (Bb Db F)
- D major: D – F# (F# A# C#) – G (G B D) – Gm (G Bb D)
Using inversions
Play the chords with inversions so the right hand moves as little as possible. Keep any common note in place. From G to B major, the note B is shared, so leave it where it is. B to C has nothing in common, so slide the same shape up. C to Cm needs only one note to move: E drops to Eb.
For example, starting from G in second inversion: D G B → D# F# B → E G C → Eb G C. Practise from all three starting points: root position, first inversion and second inversion.
Extended harmony options
- Replace the III chord with a rootless B7 (D# F# A), since the left hand already plays B.
- Or keep G in the bass and play G augmented (G B D#) as the second chord.
- Play the IV as a C major 7th without the root, which is effectively E minor over C.
- Play the iv as C minor 6 (C Eb G A).
- In D major, try Gm over Bb in the bass.
If these feel too advanced, the plain triads do the job perfectly well.
Left-hand patterns (all in 4/4)
- Semibreves: hold a root octave for four counts while the right hand plays four crotchet chords, a 1:4 ratio between hands.
- Minims: play the octave every two counts.
- Toggling minims: play the root, then the octave above, two counts each, for pitch contrast.
- Toggling crotchets: root, octave, root, octave on every beat.
- Disco eights: toggle root and octave in eighth notes.
- Ballad ghost notes: the pinky holds the root only every two beats (or for a whole bar), while the thumb plays the upper octave in steady eighth notes. Play the thumb very softly so you mostly hear the right-hand chords and the pinky's root. This takes some finger independence: hold the low note with your finger rather than the pedal.
Right-hand patterns
- Block chords: play each chord four times in crotchets, or change chords every two counts.
- Broken chords: split the chord into the top two notes, then the bottom note, giving an eighth-note feel. Toggling crotchets in the left hand fits this especially well.
- Arpeggios: play the notes one at a time in 16th notes. A suggested shape is high, low, middle, low, repeated.
How to practise
Learn the progression in G, F and D with smooth inversions first. Then combine each right-hand pattern with each left-hand pattern, always starting with semibreves before moving on. Keep experimenting with inversions so the right hand never has to slow down, and in a real song, switch between patterns for variety.
Questions about this lesson
What chords are in the Creep progression in G major?
The chords are G major, B major, C major and C minor, which is I – III – IV – iv. The B major and C minor chords are outside the G major scale, which gives the progression its bittersweet sound.
How do I make the chord changes smooth on piano?
Use inversions and keep any shared note in the same place. For example, D G B moves to D# F# B, slides up to E G C, then only E drops to Eb for C minor.
What are ghost notes in a left-hand ballad pattern?
The pinky holds the root only every two beats while the thumb plays the octave above in soft eighth notes. The thumb notes should be barely heard, so the right-hand chords and bass root stand out.
How do I play a right-hand arpeggio pattern for ballads?
Play the chord notes one at a time in 16th notes rather than together. A useful shape is high, low, middle, low, repeated over each chord.
