ABOUT: Piano Technician Philip Balke weighing-off a piano action. The keyboard must have a consistency of touch, one that creates confidence. This is controlled by regulating the piano's touch weight, much of which is done through the action weigh-off process. This entire process comes into play near the end of the piano restoration process. Once the action stack is rebuilt with new parts and initial regulation is completed, the weigh-off technician begins taking their measurements.

Highly accurate brass gram weights are used to measure both the down-weight (the amount of weight needed to depress the piano key) and the up-weight (the maximum amount of weight the key can lift during its return to its resting point). Traditionally on a Steinway & Sons Grand Piano, the down-weight is around 50-52 grams and the up-weight comes in at around 28-30 grams in the center of the piano.

When down-weight is too high, the piano can feel very heavy and be tiring to play. When it is too light, there is too little control. When up-weight is too high, the pianist often feels like the key is 'chasing' their finger and the piano can feel very heavy as a result. When it is too light, the pianist can easily outpace the instrument during fast repetitions. #Craftsmanship
