Piano key leveling

Over time, the felt underneath the keys as well as the felt in the action becomes compressed, piano key leveling. Between this settling of the felt and dry rotting of paper and cardboard spacers not to mention rodent infestations the keys of many pianos tend to undulate up and down all the way across the length of the keyboard. This can also be caused by damage to the keytops.

Uneven keys are an unsightly side effect of a well-loved piano. If you play your piano a lot or not! Over time, the material loses its integrity and the keys settle out of alignment. It's an aesthetic issue, true, but when the keys are left out of whack, play can be affected. It can feel spongy, wobbly, or just "off," making it less pleasant or even trickier to play.

My tech went to do some regulation on my Petrof IV and he mentioned leveling the keys. I never noticed that they had been not level. He did his work, but at the time I was more interested in the tone of the piano, not how the keys looked. After his work, the piano felt fine even but now when I look at the keys they indeed look uneven or not level with one another.

A level is an optical instrument used to establish or verify points in the same horizontal plane in a process known as levelling. It is used in conjunction with a levelling staff to establish the relative height or levels the vertical separation of objects or marks. It is widely used in surveying and construction to measure height differences and to transfer, measure, and set heights of known objects or marks. It is also known as a surveyor's level, builder's level, dumpy level or the historic "Y" level. It operates on the principle of establishing a visual level relationship between two or more points, for which an inbuilt optical telescope and a highly accurate bubble level are used to achieve the necessary accuracy. Traditionally the instrument was completely adjusted manually to ensure a level line of sight, but modern automatic versions self-compensate for slight errors in the coarse levelling of the instrument, and are thereby quicker to use. The optical level should not be confused with a theodolite , which can also measure angles in the vertical plane. The surveyor adjusts the instrument's level by coarse adjustment of the tripod legs and fine adjustment using three precision levelling screws on the instrument to make the rotational plane horizontal. The surveyor does this with the use of a bull's eye level built into the instrument mount. The surveyor looks through the eyepiece of the telescope while an assistant holds a vertical level staff which is graduated in inches or centimeters.
