Bring Piano Chords to Life With Ghost Notes and Swing (Double-Thumb Trick)
To make piano chords groove, feel each beat divided into swung eighths or triplets, then bring that subdivision out with broken chords and arpeggios in the right hand, soft root, octave and fifth ghost notes in the left hand, and both thumbs working together.
Key points
- Time feel is how you hear each beat divided: swung eighths (by two) or triplets (by three).
- Break a right-hand chord on one beat: outer notes together, then the middle note, swung.
- For triplets, use a three-note arpeggio so each chord note fills one triplet.
- Left-hand ghost notes are soft extras, such as the octave and fifth (C and G over a C root).
- The double-thumb trick pairs both thumbs with left-hand octaves for a richer, more epic triplet texture.
What this lesson teaches
This is Part 3 of Jason Zac's five-part series on making a chord progression stand out. Part 1 covered dynamics, staccato and legato, and following the drummer. Part 2 built a melodic bass line. Here the focus is time feel: how you sense each beat being divided, and how you let that division show in both hands.
It suits pianists who can play a simple progression and want it to sound groovy and human rather than stiff and programmed. Jason also suggests that music producers improve their actual playing instead of drawing notes with a pencil tool in a DAW. Real playing is faster and has far more character.
Two time-feel worlds
A beat can be divided into any number of parts. This lesson uses two:
- Divide by two, swung: count 1 and 2 and 3 and 4 and, with the eighth notes swung.
- Divide by three: eighth-note triplets, counted 1 and a 2 and a 3 and a.
Even when you play on the pulse, try to feel these subdivisions inside you. The techniques below simply bring that inner feel out onto the keys.
Step 1: Start with a simple bass
Put the Part 2 bass line aside for now. Have the left hand play a plain root-note bass, one note per chord, so you can focus on the right hand.
Step 2: Broken chords in the right hand (swung)
Keep the right hand mostly on block chords, but break the chord on one chosen beat. Jason uses beat 3 and splits it into two swung eighths.
- Play the outer notes of the chord together, the lowest and the highest.
- Then play the middle note on the swung off-beat.
You can also reverse the idea. Play the top two notes together, then weave in the bottom note. You can break the chord on any beat, such as beat 2 or several beats. Jason chooses beat 3 to keep it simple.
Step 3: Arpeggios in the right hand (triplets)
For the triplet feel, an arpeggio works better than a two-part break. The chord has three notes and the beat is divided into three, so each chord note fills one triplet. A pattern of chord hits followed by a quick arpeggio gives a strong triplet vibe. You can also give the arpeggio a slightly broken feel, or go fully into triplets on every beat.
Step 4: Ghost notes in the left hand
Now return the right hand to its original simple chords and let the left hand add ghost notes. These are soft extra bass notes that add flavour and reveal the time feel, either swung or triplet.
On a C chord:
- C is the main note.
- The octave C is one ghost note.
- The fifth, G, is another.
Play the ghosts noticeably softer than the main note, in a triplet rhythm counted 1 and a 2 and a. You could keep using C for the next chord, but C does not sound good under the F chords. Move the ghost notes to F there.
Step 5: The double-thumb ghost trick
For this trick, the left hand plays octaves while the right-hand thumb and left-hand thumb work together to fill in the triplet subdivision. The result has many more notes and more dynamic movement. It gives an epic character that suits an alternate section of a song. Jason uses this trick often in his own music.
How to practise
- Count the subdivision aloud before you play: swung eighths first, then triplets.
- Practise each technique on one chord, then spread it across the progression.
- Keep ghost notes soft. They should be felt more than heard.
- Mix the ideas between song sections. Try ghost notes in one part and right-hand broken chords in another.
- Do not aim for machine-perfect timing. Small differences in length and loudness make your playing sound like you.
Part 4 moves on to chord voicings and inversions for building themes.
Questions about this lesson
What are ghost notes on piano?
Ghost notes are soft extra bass notes added in the left hand to bring out the time feel. Over a C chord, for example, you play C as the main note, then the octave C and the fifth G more softly in a triplet rhythm.
How do I play a swung broken chord in the right hand?
Pick one beat, such as beat 3, and split it into two swung eighths. Play the lowest and highest chord notes together, then the middle note. Alternatively, play the top two notes together and then the bottom note.
Why use an arpeggio for a triplet feel?
A triplet divides the beat into three, and a basic chord has three notes. An arpeggio lets each note fall on one part of the triplet, which makes the feel very clear.
What is the double-thumb trick?
The left hand plays octaves while the right-hand thumb and left-hand thumb work together to fill the triplet subdivisions. This gives a fuller, more dynamic sound that works well for an alternate song section.
