3 Go-To Left-Hand Piano Patterns Every Player Needs
Three dependable left-hand piano patterns cover most genres: the umpah (root-fifth bass with a staccato chord), the four-note arpeggio (low, high, middle, high), and the power chord (root, fifth and octave) played in different rock rhythms.
Key points
- Umpah: alternate the root with the fifth below it and a staccato chord, keeping the bass legato.
- Arpeggio: play low, high, middle, high (D, A, F, A on D minor), then add the octave for an eight-note version.
- On seventh chords the upper copy can become the seventh; on slash chords like C/E the bass note E becomes the low note.
- Power chord: root, fifth and octave, played in rhythms like four on the floor, accented eighths or hits on beats two and four.
- Practise each pattern over many chords and progressions with a relaxed wrist, then trust the left hand.
What this lesson teaches
If your left hand feels like the weakest part of your playing, this lesson from Jason Zac at Nathaniel School of Music gives you three tried and tested accompaniment patterns. They work across old-school peppy songs, swaying ballads, pop and heavier rock. It suits players who have been playing for a few months to a year or so, though beginners can follow along and plan ahead. The aim is not to teach particular songs but to give you patterns you can apply to any song, key or chord.
Pattern 1: The umpah (accordion) pattern
Take a chord such as D minor (D F A). Play the root D in the bass, then reach down a fifth with your little finger to the A below. Alternate between the bass note and the chord: bass, chord, bass, chord, so the rhythm sounds like oom-pah, oom-pah.
- Articulation matters: the chord part (the pah) should be staccato, short and light, while the bass movement can be legato.
- Three-four version: play one bass note followed by two chords for an oom-pah-pah waltz feel.
- Modern version: shift the rhythm into a more syncopated feel and move the bass around between root and fifth for a contemporary sound.
- Beginner version: if the open-and-close hand movement feels hard, simply break the D minor chord, alternating bass note and the rest of the chord within one hand position.
Try it on different chords, and add a simple melody or nursery rhyme in the right hand (switch to a major chord for rhymes).
Pattern 2: The arpeggio
The basic shape uses four notes of the chord in the order low, high, middle, high. On D minor that is D, A, F, A, repeated. Move it to other chords such as E major (E, B, G#, B) or E minor (E, B, G, B).
Adding the octave
For a fuller, more advanced sound, extend the pattern to eight notes: low, high, middle, high, then the octave of the low note, high, middle, high. On D major that is D, A, F#, A, upper D, A, F#, A.
Seventh chords and slash chords
- On a seventh chord, the upper note does not have to copy the bass note; it can be the seventh of the chord instead.
- On a slash chord such as C/E, play E in the bass. E becomes your low note, and that is the note you copy at the octave.
Arpeggios must be dynamic. Use swells and careful volume control, as this is what makes them sound musical. Jason demonstrates the pattern over tunes such as Ode to Joy and songs in the style of Elton John and the Beatles, including a minor seven flat five chord.
Pattern 3: The power chord
A power chord is simply a root, fifth and octave, for example D, A, D, played powerfully in the lower part of the keyboard. Try contrasting rhythms:
- Four on the floor: steady hits on every beat.
- Driving eighths: play eighth notes and add accents to push the groove.
- Broken patterns: break up the rhythm for variety.
- Beats two and four: hit where the snare drum would land.
- Floating the fifth: let the fifth move or float above the root for colour.
How to practise
Pick at least one song for each pattern and explore it in a key of your choice. Practise each pattern over different chords, majors, minors and even chromatic movement, and then over full progressions. Learn which chord degrees a song uses so you can write out and transpose the pattern into any key.
When playing fast, especially arpeggios, use a relaxed, floating wrist and your whole arm so you play without pain. Once the patterns are secure, trust your left hand and put your attention on the melody and the audience. If you run out of songs, nursery rhymes like Twinkle Twinkle Little Star or simple improvisation work perfectly.
Questions about this lesson
What is the umpah left-hand pattern on piano?
It alternates a bass note with a chord, like an accordion. On D minor you play D in the bass, then the A a fifth below, alternating with a short staccato D minor chord above.
What order do I play notes in a left-hand arpeggio?
The basic shape is low, high, middle, high, using the root, fifth and third of the chord. On D minor that gives D, A, F, A, and you can add the upper octave of the root to make an eight-note pattern.
How do I play a left-hand arpeggio on a slash chord like C/E?
Put the bass note E at the bottom and treat it as the low note of the pattern, copying it at the octave when you use the extended version.
What is a piano power chord?
A power chord is the root, fifth and octave of a chord played strongly in the left hand. It suits rock when played as steady beats, accented eighth notes or hits on beats two and four.
