An instrument made by one single luthier from the beginning to finish: ideally done by the luthier who has good knowledge, massive experience in each step of making, so the maker can have total control from tone wood selection, arching, graduation, to the varnish.
Depending on each maker's approach, some are making one violin at a time, while some are making 2-3 instruments at a time, for a better balanced, consistent tonal result. The average time in making also varies, as some prolific makers can make up to 3-4 instruments per month, excluding the varnishing time.
