|
|
A viola player in the local chamber ensemble I play in, is complaining that when she lifts the bow from the string, any string, the pitch drops perceptively. I'm trying to think of a cause that might be related to the bridge, but have not read anything or heard of this before. Any thoughts? _________________ Dave in the Blue Ridge

I'll place two bets on this, not with 100% certainty; more like 60%:
1/ it only happens on the open A
2/ it's an adjustment problem, but she won't be able to find anyone who can adjust it.
If it's on all strings, what brand is she using (some off-track brand because it's cheap, I suspect--this is a characteristic of soft, cheap strings designed for beginners--Piranitos for cello, do this, for instance)? |

sounds like a string tension issue. which be a deeper issue of having the correct stringth length ratio. so, maybe not fixable. trying different guage (thinner) might help the problem.... _________________ http://sgwhiteviolins.googlepages.com/home |

I recently set up a cheap violin and for the heck of it used the el cheapo strings that came with it just to see what was up with them.
THey were horrible and I noticed a distinct change in pitch when playiing th estrings. Switched to dominants and the problem was gone.
I would first look at the strings as the culprit!

I've asked the young lady to get all new strings before we tackle any other issues. She'll probably get Dominants or Obligatos (which seems popular in our string section). Thanks for all your input on this. It was something I just had not heard of before, and could not think of what might be the source of the problem. So, we'll get the new strings on and see if that solved the problem. _________________ Dave in the Blue Ridge

i forgot to mention that strings that are on the verge of going bad (false) can lose pitch quite easily. _________________ http://sgwhiteviolins.googlepages.com/home |

If the new strings don't cure this, we'll take a look at string length ratio.
By the way, enjoyed the photos of your shop setup and stuff you're working on. I'm finally getting around to rewiring my shop, instead of 2 outlets with forth-thousand lead cords going hither and thither. Meanwhile, I call it "the dungeon." _________________ Dave in the Blue Ridge

hi dave,
thanks for the nice compliment!
hope the strings cure the issue and it is not a string length ratio issue. as that is not really curable. or easily curable, that is..... _________________ http://sgwhiteviolins.googlepages.com/home |
