Piano accompaniment: what should your left hand play?The same chords. Six ways to bring them to life.

What should your left hand play for piano accompaniment?

The left hand can provide bass, harmony and pulse. It does not need to do everything at once. A held root with a simple right-hand melody already forms an accompaniment. Add chord tones or a rhythmic pattern next.

The demonstration keeps the same harmonic functions: I–vi–IV–V, or C–Am–F–G in C major. Change just the pattern to hear how rhythm transforms it. In the waltz, each chord lasts three beats instead of four: compare the movement rather than trying to overlay the metres.

1. Find each chord’s root and play it on its own.
2. Count aloud without speeding up at chord changes.
3. Add the other notes, then practise one bar of the pattern.

Six piano accompaniments to hear and practise

Count the beats before increasing speed

In 4/4, count 1–2–3–4. To locate eighth notes and offbeats, say 1 and 2 and 3 and 4 and. Offbeats fall between the pulse, not after an approximate pause: keep the numbers steady even when you do not play on them.

Count a waltz 1–2–3. Shuffle uses a triplet-based subdivision: the two attacks in a beat are not equally spaced. In this demo’s pattern, hear the long note followed by a short one, then try that feel on one note before returning to the chord.

Choose a tempo at which chord changes stay relaxed. If your hand tenses, slow down or return to a single root. One steady bar gives more useful reference points than a full progression interrupted by unplanned stops.

Chord positions, register and pedal

Close chords in a very low register can become difficult to distinguish. Try a low bass note with the other notes higher up. To reduce movement, find a shared tone between two chords and keep it when the position allows.

An inversion changes which chord tone is in the bass. C–E–G, E–G–C and G–C–E are three C-major arrangements. Try them in the dictionary, then choose a position suited to the next chord. Fingering depends on your hand and the following movement.

Practise without pedal first so you can hear attacks and chord changes. Add it carefully later: pedal held across harmonies can blur the notes. The browser demonstrates the pattern; on your piano, touch and note lengths shape the result.

Add a right-hand melody gradually

Stabilise one bar with your left hand. With your right, play one chord tone on the first beat and hold it. Repeat until you can count while playing. Add a second note next, then a short motif with a breath.

Over C, try E–D–C in the right hand above a held chord. Keep that little phrase when changing the accompaniment: hear which changes come from the melody and which from the rhythm. The Impro workshop then lets you practise the hands separately before combining them.

Create your own starting point

Once comfortable with a pattern, try another key or progression at the same tempo. Change one thing at a time so you can identify what helps. The chord generator offers progressions; the dictionary shows their piano keys.
