Scroll Tuning Page....
...Now that the violin scroll is mostly carved turn our attention to the final shape of the scroll. You do this step prior to varnish of couse. The varnish will not effect the tap tone tuning; either here or on other parts fo the violin.
...When we tap the scroll shapes perpendicular from the top, bottom, front or back, we want this tap tone to be the same as the back plate {198 HZ/ G below middle C on the piano). Follow all the turns of the scroll up to the center terminis. See photo A below:
...When we tap the side surfaces of the scroll, we want the tap tone to be the same as the center of the top plate ( 176HZ; approximately F below middle c on the piano keyboard). See photo B below:
... When we lower one, the other raises in the same area.
...When properly tuned, both these conditions exist at the same time!
...This will also help with the beauty and brilliance of the tones played.

... I want to express my thanks to Pierre Lieba for his work on scroll tuning and his encouragement that it is an important area to tap tune.

..tune all these to 198 HZ. (Same as back plate). If too low, take material from the side surface below tap. If too high, remove a slight amount from the outside edge or deepen the channel nearby.
Photo B.
..Tune all these areas to 176 HZ (same as top plate). Should be even tap tones all over the side surfaces: scrape down any high toned area.
....If too high, remove material from high areas until tap tone equals 176HZ.
..If too low, remove material from immediate outside edge to raise tap tone.
