What happens when you hit a piano key?
When you press a key on the piano it causes a small hammer inside the piano to hit a string or strings. Each key is connected to its own hammer or hammers which hit a specific string or number of strings. When the hammer hits a string, it vibrates and makes a sound that is tuned to a specific note.
Why do my piano keys feel heavy?
Over time, dirt, dust, wear and tear can change those specifications making the touch of your piano keys feel heavy and sluggish. Cleaning, lubrication and action regulation will usually restore, and often make better, the original touch and feel of your piano's keys.
