What is Regulation?
In a nutshell, regulation is making adjustments to the playing mechanism back to the factory setting.
Why should my piano be Regulated?
Speed & Repetition – When everything is in working order and aligned properly this allows the parts to reset and run smoothly.
Control – When all the keys are working properly and timed to work equally it will react the same whether you play a heavier bass key or a lighter high tenor.
Dynamics – With the hammers all releasing at the same close distance and all the other operations being equal this allows you to have maximum control of the dynamics, most noticeably quietly.
