Pedagogical Guide: How to Accompany on Piano
Accompanying on piano is not about playing static block chords. Piano playing comes alive when chords are rhythmically arpeggiated across both hands.
The left hand anchors the harmony using roots, fifths, and octaves (1-5-8). Keep this register warm and controlled to support the mid-register without muddiness.
The right hand articulates the color tones (third and fifth) in rolling rhythmic pulses that provide continuous forward motion.
Engage the sustain pedal immediately after striking the downbeat, and clear it precisely on each chord change to maintain harmonic clarity.

How to use it
How to practise piano arpeggios
A piano arpeggio plays the notes of a chord one after another, not all at once. It helps you practice thumb-under, lateral hand movement, and making each finger sound even.
It's also one of the most beautiful ways to accompany a melody.
Listen: the progression as arpeggios
- C
- Am
- F
- G
A step-by-step method
- Start with a single octave and one hand. In C major, the right hand plays C, E, G, and C with fingers 1-2-3-5. Listen to make sure each note sounds equally loud.
- Once one octave flows smoothly, move to two. When ascending, the right thumb passes under the third finger. When descending, the third finger crosses over the thumb.
- Keep your wrist loose and level, and let your forearm accompany your hand. The thumb moves ahead to the next key before pressing it.
- Practice each hand separately, then both together, one or two octaves apart.
Posture and Arm Weight
Don't press hard with just your fingers or tense your forearm. Shift the weight of your arm from one fingertip to another, as if walking across the keyboard.
Keep your shoulders low and your elbow free. This allows it to move sideways when the notes go to the higher or lower registers.
Tempo and Rhythm
Set the metronome to a tempo that allows you four clean repetitions. Group three or four notes per beat to feel where the accents fall.
Gradually increase the speed.
Play the same arpeggio with alternating rhythms, long-short or short-long. This greatly helps to even out weaker fingers.
From Exercise to Music
Once the arpeggio feels secure, use it with the chords of a progression, like piano chord progressions.
Moving from one chord to the next without losing the arpeggio's pulse is what turns the exercise into an accompaniment.
