The Piano Engine: Build Finger Independence With One Epic Theme
The piano 'Engine' is a driving accompaniment where the left-hand thumb keeps a steady pulse while the pinky holds longer notes, the right-hand thumb adds a third on the last sixteenth of each beat, and the remaining fingers play a simple melody on top.
Key points
- Finger independence means individual fingers in one hand playing different rhythms, not just the two hands doing different things.
- In the left hand, the thumb keeps a steady pulse on G# while the pinky plays whole notes, half notes or one note for every two or four thumb notes.
- The right-hand thumb plays the third of each bass note on the 'a' of every beat (1 e and a), creating the gallop.
- Keep the melody simple because the Engine underneath is rhythmically dense.
- Practise slowly, count aloud and try the Engine at soft and loud volumes and with different accents.
This lesson from Jason Zac at Nathaniel School of Music teaches a pumping, cinematic rhythm he calls the Engine. It is inspired by the motor sounds of trains, trucks and tractors. Along the way it trains finger independence, which is different from hand independence: here individual fingers within one hand do different rhythmic jobs. It suits intermediate pianists who already play simple chords in both hands.
Step 1: The left-hand pulse
Place your left-hand pinky and thumb on two G# notes (also called Ab), an octave apart. Play them together as steady quarter notes (crotchets), counting 1, 2, 3, 4. You can use the sustain pedal or play without it.
Step 2: Separate the pinky and the thumb
- Whole notes: hold the pinky down on G# while the thumb keeps playing the quarter-note pulse.
- Half notes: let the pinky strike only on beats 1 and 3 (minims) while the thumb continues every beat.
- Eighth notes: speed the thumb up to eighth notes, counting 1 and 2 and 3 and 4 and. The pinky can now play once for every two thumb notes, or once for every four.
Notice how the two fingers sometimes strike together and sometimes at different points. This is the foundation of the pattern. Once it feels steady, move the bass around the G# minor scale, trying notes such as E, D#, F#, B and C#.
Step 3: Sixteenth notes in the right hand
Now go deeper into the beat by counting sixteenths: 1 e and a, 2 e and a, 3 e and a, 4 e and a. A useful strategy is to practise this with a shaker or your voice, saying the main beats strongly and the other syllables softly.
The left hand already covers the beats and the ands. The right-hand thumb now targets the a, the last sixteenth of each beat. Over the G# bass, start with a B. Jason Zac also calls this the gallop. Go slowly and aim to feel it rather than count it.
Use the third of each bass note
As the bass moves, the right-hand thumb plays the third above it:
- G# with B
- F# with A# (Bb)
- C# (Db) with F (strictly E#)
These pairs outline chords. A progression moving from G# through F# to C# already sounds very much like a film theme. You can play the gallop softly so it is felt rather than heard, or accent it so the groove pumps harder. You can even try the whole thing with a swing feel.
Step 4: Add the melody
The melody is deliberately simple because everything underneath is busy, like a long line a string section might play. It moves through notes including B, A#, F#, D# and G#, counted slowly across the bar. Learn it alone first, then add the left-hand pulse, and finally the gallop.
You can thicken the right hand with extra notes. Adding G# with D# over an E bass completes an E major seventh chord (E G# B D#). Adding F# with B over the G# bass spells a G# minor seventh (G# B D# F#).
How to practise
- Work slowly and do not let the piano run away from you.
- Count or sing along, or use a drum backing track, to lock in the time.
- Practise the Engine at different volumes, from very soft to loud, keeping the pinky and thumb separate throughout.
- Try making the a a little louder. Accenting one subdivision is what drummers, percussionists and guitarists do to create a pumping feel.
Once the Engine runs on its own, you can use it as accompaniment for a singer or another instrument, or improvise your own melody over it with the fingers that are still free.
Questions about this lesson
What is the difference between finger independence and hand independence on piano?
Hand independence means the two hands play different parts. Finger independence means fingers within the same hand, such as the left-hand pinky and thumb, play different rhythms at the same time.
Which notes does the right hand play in the Engine pattern?
The right-hand thumb plays the third above each left-hand bass note, such as B over G#, A# over F# and F (E#) over C#. It lands on the 'a', the last sixteenth of each beat.
How should I count the sixteenth-note gallop?
Count 1 e and a, 2 e and a, and so on, saying the main beats strongly and the other syllables softly. The left hand covers the beats and ands, and the right hand adds the 'a'.
Can I use the Engine without the melody?
Yes. The rhythm on its own works as a strong accompaniment for a singer or another melody instrument, and you can also improvise your own tune over it.
