Violins need regular maintenance. Violinists usually change their own strings and clean and polish their instruments, as well as make minor bridge adjustments. Most will not attempt a bow rehair, “cutting” a new bridge, or even a sound post adjustment, much less anything involving the varnish or structure of the violin. Businesses, like violins, also need regular maintenance. What needs to be done may well depend upon the type of business and how many owners and employees it has.
