You may have noticed that the feel on some pianos is heavier than on other pianos. But did you know that the keys on any piano are different weight across the keyboard? All pianos have gradually heavier feel the lower you play on the keyboard! There are 2 reasons for this you can observe if you look inside a piano:
The keys (behind the fallboard) get longer and longer as you get lower across the keyboard.
The hammers are thicker and heavier the lower you go on the keyboard.
This is why the keys on pianos are harder to push down in the bass section than in the treble. You are moving more mass with longer keys and heavier hammers the lower you play on the keyboard.
Digital piano manufacturers attempt to mimic this feel by creating different weight in zones across the keyboard. Soon, there will be a digital piano on the market which will have a truly weighted-graded action transitioning smoothly from key to key across the entire keyboard, not just in zones. Stayed tuned to Living Pianos to hear about this new technology!
