Digital Pianos Explained: How They Work and What Sets Them Apart
A digital piano aims to capture the sound and feel of a real acoustic piano in a compact, affordable, and maintenance-free instrument. If you’re new to them, here’s what makes a digital piano tick.
What is a digital piano?
A digital piano uses recorded samples of a real grand piano — or modeled sound — played back through built-in speakers when you press a key. Unlike a basic keyboard, it focuses on recreating the authentic piano experience above all else.
Weighted keys: the most important feature
Real pianos have hammer action — keys feel heavier in the bass and lighter in the treble. Quality digital pianos replicate this with weighted, graded hammer-action keys, so your technique transfers directly to an acoustic piano.
Sound and polyphony
Two things shape the sound: the quality of the piano samples and the polyphony (how many notes can ring at once). Higher polyphony — 128 notes or more — prevents notes from cutting off during rich, pedal-heavy passages.
