A website for the serious amateur violin maker, restorer and tinkerer.    A violin front and back (the plates) can be tuned using tap-tones.    Use tap tones to adjust the 2 plates of a violin to get the best sound, the kind of sound you want, or make an instrument that is easy to bow.

This site has something for you if you are either making a violin or you want to improve  a low cost violin or viola.

By tuning the top & back plates you can get a good instrument that responds well to the bow and that can sound like a £1500 instrument.

Here are more details on some of the instruments I have modified:-

A good modern Chinese violin c. 1980,

JTL Medio Fino, Marked “Steiner”.

German “Bench fiddle”, circa 1800  marked ‘Hopf',  with a ‘transitional' neck, dating from the early 1800's. I lengthened the neck at its root.

a 15 1/4” (387 mm) Viola, modified to have low plate stiffness factors, and making an outstanding student / orchestral viola!

a German (transitional *) fiddle with a lions-head scroll, also dating from the early 1800's. It had such a low belly Mode 2 that I needed to add 5 cross-braces to raise Mode 2 and also improve the ring/Mode 5 resonances.  An outstanding tone - a delight to play.

A violin labelled “John Juzek, Prague”. 

A German Stainer copy, a 7/8ths Christian Meisel (1930),  and a good Mittenwald, with very dark varnish that once had a severed peg-box.

 These violins now have a known, reasonably matched ‘stiffness factors' (which is the ratio of plate stiffness figure to the Reference plate stiffness, as given on this page) on both front and back.

 * With a short neck, the kind fitted before ~1820.

There is also a page on the violins and violas at the Ashmolean Museum in Oxford, UK here. This includes the Stradivari “Messiah” violin.
