How Many Parts are There in a Piano?

Piano Lessons / piano parts / How Many Parts are There in a Piano?


It’s fascinating to think about how many parts there are in the average piano. Think about how many string there are, how many keys there are, and then how many moving parts are involved with each press of a key; it’s daunting to think of just how many parts there are in a piano!


A typical scale design has around 220-240 strings. In the bass section there are 1 or 2 strings per note. Each one of these strings has a tuning pin as well. We haven’t even gotten past the strings and we already have hundreds of parts!


Most notes on a piano have dampers and damper heads (hundreds more parts). Consider the furniture of the piano, the rim, lid, prop stick, legs, the pedals, and more, and there is the soundboard, pinblock, agrafes, bridges and plate.


Believe it or not, we haven’t even scratched the surface for the parts on the piano! The action of the piano is where the majority of the parts are. When you push a key on a piano you are setting in motion around a hundred parts – that’s for each key!


So how many parts are there on a piano? Around 12,000! Hopefully this gives you a better appreciation of just how complex these instruments are and what it takes to build and service a piano.
