....This graduation plan is a combination of a Strad graduation with my experience in plate tuning. It has shown to give consistently good instruments with plate frequencies of 322 HZ top plate and 353.5 HZ back plate (after fine adjusting). It should help you achieve a completed violin weight (ready to play) of around 400 grams (not counting the chin rest).
...When you have graduated your plates carefully to this pattern, the next step is to tap along the diagonal lines through the center of the plates and listen for higher toned areas, especially at the transition areas into the thin upper and lower bout areas.
...These transition areas that are higher toned need to be scraped down until there is a smooth tone transition along the diagonals. The diagonal tapping is important because the overtones along these lines are similar so easier to hear and understand.
...Once this step is accomplished, we want to raise the plate frequencies to 322HZ top plate and 353HZ back plate. Our main goal is to make the upper and lower bouts tap tones match each other and the goal frequency.
...See article on plate tuning in index for more details on how to do this.
