More on Action Regulation

What's Action Regulation?

The mechanical part of the piano is called the Action. The tolerances in the relationships between the parts in each key are critical to how efficiently the key operates, which translates into how easy it is to play. Those tolerances change as the piano ages, felt parts compress, metal parts wear out wood, etc.

Depending on who's counting, there are roughly 12 to 16 different adjustments that need to be made for each key. 88 keys times 16 adjustments is 1408 adjustments if everything needs to be changed. The good news is that it's rare to have to do all of them.

The reason the price varies a lot is that doing Action Regulation is like peeling off layers of an onion: you don't know what the next layer looks like until you finish this layer. Often you do two or three sets of adjustments, and all the rest fall into place. So I usually quote the high-end price, and most of the time it doesn't cost that much.

Why should I get an Action Regulation?

A piano that is hard to play is hard on your psyche. You feel like you can't play well anymore. I've seen people sell pianos or give up playing altogether when all they needed was a couple hundred dollars worth of Action Regulation to make them feel like musicians again.
