A single note fails to vibrate correctly- violin broke ?
Hi. I bought a used Chinese made scherle roth violin. The original price was 300 USD so it's a low end instrument. The notes all sound fine except the A string's c sharp note. When I play it it vibrates abnormally with cross tonality. In other words imagine hitting c and csharp on a piano at the same time - that's how it sounds.
This isnt a case of me putting any vibrato on the string through my bow or finger pressure. This isnt a case of accidentally hitting the E string at the same time. It doesnt occur on other notes. It does occur on the lower d string at the 11th "fret" which is the c sharp there.
Naturally I replaced the string and examined the head and bridge and soundboard for imperfections but cannot locate the source of the jittering sound.
Any thoughts? Playing D or C sounds fine but the Csharp whirls like a helicopter sound when it takes off.
That's called a "wolf tone", and it's awful for it to occur where you have it.
A luthier may charge more than the price of the instrument to cure this.
Adrian -- that's the usual "easy fix" (if there is one), but I've always wondered why that particular spot.
I found this zone by trial & error. With the violin on my lap and a small clamp to on the A-string to try different notes, I could bow while pressing gently on different parts of the violin. The notes around A,B,& C seem to come from large areas of the top plate, but particularly the part I described.
Many thanks for all the comments. I will do some research on the wolf tones and try some of these recommendations! Very fascinating effect physics wise - if only I could turn it off and on at will. Will try to remove
A few random thoughts (late at night - yawn!) . . .
$300 for a violin is so cheap you should be glad you only have one bad note.
Spending time and energy in this case is actually a useful learning experience, not least from the comments.
In addition to the chinrest, check the fine tuners. I'd also recommend carefully going all the way around the perimeter of the instrument, top and back, pulling the plates away from the sides to see if you can find any open seams, however small those openings might be. And if you find any openings, don't let your local handyperson glue it, because they'll almost certainly use the wrong glue. Take it to the violin shop.

Demian, I don't see this as being rude, as much as educational.
There are plenty of people who might like to try their hand at the violin for whom $300 is a lot of money. Let them eat cake I guess.
