Piano tuning is the act of adjusting the tension of the strings of an acoustic piano so that the musical intervals between strings are in tune. The meaning of the term 'in tune', in the context of piano tuning, is not simply a particular fixed set of pitches. Fine piano tuning requires an assessment of the vibration interaction among notes, which is different for every piano, thus in practice requiring slightly different pitches from any theoretical standard. Pianos are usually tuned to a modified version of the system called equal temperament.

plus tuning fee

Pianos are generally tuned to an A440 pitch standard (A above middle C vibrates at 440 hz per second) that was adopted during the early 1900s in response to widely varying standards. A 'pitch raise' or 'pitch correction' or 'double tuning' is the term used to describe the process of changing the pitch of a piano prior to a fine tuning when the pitch has shifted more than 10% of a semi-tone. In these cases, the piano needs to be tuned more than once ($50+tuning fee). If the piano is more than 50% below pitch, it will need to be tuned two to three times ($90+tuning fee). If the piano is more than 100% flat, it will need to be tuned three or more times to bring it to A440 ($120+tuning fee). If you would like to know the pitch of your piano prior to the piano visit, text a video playing A above middle C to 703-657-9404.

Half Day of Service


A four-hour piano service (please set aside 5 hours for run-over-time) which encapsulates whatever I can accomplish, in order of priority, within that time frame. Usually it consists of a pitch raise - if needed, tuning, cleaning, and action adjustments or voicing or repairs. If your vertical piano hasn't been serviced for ten years or more, a Half Day of Service is a good course of action.
