How to Play a Melody With 5 Left-Hand Chord Accompaniment Techniques on Piano
To accompany a right-hand melody on solo piano, keep the right hand on the tune and give the left hand the chords, using one of five patterns: block chords on the pulse, eighth- or sixteenth-note arpeggios, broken chords, spread 1-5-3 voicings, or stride (low bass note then a chord near middle C).
Key points
- In solo piano the right hand carries the melody, so the left hand handles chords, voicing and groove.
- Keep block triads around middle C; low close triads sound muddy.
- Arpeggio pattern: low, high, middle, high; the sixteenth version lifts the low note an octave in the second half.
- Spread voicings play 1-5-3 with the third up an octave, and need the sustain pedal.
- Stride alternates a low root (single note or octave) with a chord near middle C.
This lesson by Jason Zac of Nathaniel School of Music shows how to build a solo piano arrangement from an existing melody. In most solo piano playing the right hand is busy with the tune, so the left hand must carry the chord progression, the voicing and the groove. You learn a short piece in G minor with an A section and a B section, then five left-hand patterns that support it. These patterns also work for film scores, pop and rock songs you want to cover. It suits players who can already play simple triads in each hand.
The Melody and Chords
A section
The A melody is in G minor. Start on Bb with your ring finger; a ring finger on a black note sits comfortably. Where the line climbs, bring your pinky to the top note, then pass the thumb under so the pinky can return to the octave. This fingering makes the phrase easy to loop. Once it is secure, you can add small embellishments of your own.
The chords are G minor for a whole bar, then F for half a bar and Eb for half a bar. On the F you can use Fsus4 (F Bb C) resolving to F major (F A C).
B section
The B melody uses tied notes and many off-beat “and” hits, so count eighth notes slowly. Start with your thumb; three fingers are enough, with the ring finger optional and no pinky needed. The chords are C minor, Bb/D (a Bb chord with D in the bass) and F, again with the option of Fsus4 to F. Try singing the tune as you play, because most solo piano arrangements grow from the vocal line.
Where to Place the Chords
Block triads played low on the piano sound muddy. Keep block chords around middle C. If the melody clashes with the chords there, move the whole tune up an octave.
The Five Left-Hand Patterns
- Block chords on the pulse. Play the full triad on every quarter note, one chord hit per beat. You can also try octaves.
- Eighth-note arpeggios. Instead of striking all three notes, play low, high, middle, high (L H M H). Gm becomes G, D, Bb, D. This gentle pattern suits the soothing character of the tune.
- Sixteenth-note arpeggios. Double the speed, and for variety play L H M H in the first half, then take the low note up an octave for the second half before continuing H M H. Compare it with the slower version to hear the difference in energy.
- Broken chords. Play the root, then the top two notes together. A slow version does this in quarter notes on the pulse; a quicker version alternates the outer two notes with the inner note in eighth notes. This is a good option if arpeggios feel difficult.
- Spread voicings. Low down, a close 1-3-5 triad sounds thick, so play 1-5-3 with the third raised an octave (a tenth). Gm becomes G D Bb, F becomes F C A, Eb becomes Eb Bb G, and Bb/D becomes D Bb F. Play eighth notes followed by a longer note so you have time to move to the next chord, and hold the sustain pedal or the bottom note will vanish. With the left hand this low, you can bring the melody down an octave.
- Stride. Play the root very low, then jump up and play the chord near middle C, toggling between the two with the pedal held. Use a single bass note for an easier, still full sound, or a root octave for a more epic feel.
How to Practise
Learn each melody with its fingering first, then add simple block chords. Work through the patterns in order, from blocks to arpeggios, broken chords, spread voicings and finally stride, which is the most advanced. Once a pattern is secure in the left hand, keep it steady even when the right hand adds flourishes. Then experiment with these approaches on other songs.
Questions about this lesson
What should my left hand play when my right hand plays the melody?
The left hand takes care of the chord progression and rhythm. Start with block chords on each beat, then move to arpeggios, broken chords, spread voicings or stride as you gain confidence.
Why do my left-hand chords sound muddy?
Close triads played low on the piano sound muddy. Keep block chords around middle C, or if you play low, spread the chord as root, fifth, then the third an octave higher.
What is a spread voicing on piano?
A spread voicing plays the triad as 1-5-3 instead of 1-3-5, with the third raised an octave, so G minor becomes G D Bb. Hold the sustain pedal so the low note keeps ringing.
How do I play a simple stride left hand?
Play the root very low, then jump up and play the full chord near middle C, alternating with the pedal held. A single bass note is easier; a root octave sounds bigger.
