Piano Tuning and Repair Services
Tuning - Adjusting the tension of each string (a piano has over 200 strings) so that it sounds in harmony with the other strings. Each piano string is attached at one end to a hitch pin and the other end is wraped around a tuning pin. The piano technician then turns the tuning pin with a tuning lever until the desired pitch/tension is reached.

Regulation - Action parts (the moving parts) may need periodic adjustment to compensate for wear, compaction (of felt parts) and changes in wooden parts due to changes in humidity. The purpose of regulation is to ensure that moving parts are operating as they should and that the piano is responsive to the pianist's touch.

Piano Cleaning - Dust can collect inside a piano. Vacuuming the interior of a piano can remove a good deal of it but to do a thorough cleaning the technician may need to blow the dust out of the action and from behind/below the strings. This is accomplished by attaching the vacuum cleaner hose to the exhaust end of the vacuum.
