I carry enough tools and supplies to repair most broken parts in a single visit for a reasonable price.
Adjustments aimed at increasing the efficiency of the mechanical part of your piano are called action regulation. Frequently, relatively inexpensive adjustments can make a big difference in the sensitivity of touch, allowing you to play much more expressively. These adjustments restore the correct tolerances that were set when your piano was new, but which gradually changed over the years with use. My job is to recommend which adjustment will make the greatest improvement at the least expense.
Adjustment of the tone of a piano is called voicing. It is accomplished by making careful changes to the shape and density of the hammers. A properly voiced instrument can sound remarkably more beautiful. I enjoy this task of bringing out the greatest beauty in the sound of an instrument.
I highly recommend the appraisal of a piano prior to purchase. Pianos vary widely in quality and condition, and many need costly repairs or maintenance that are not obvious to the untrained eye or ear.
