Does anyone know if it is possible to remedy a wolf note on a viola ?
I have found the Krenz Wolf Eliminators to be very effective:
Thank you Andrew , I'm getting interested in wolf notes now . I tried attaching a little weight to the g string of my viola , this definitely works but only to a certain extent . I looked up wolf notes in "Violin Making As It Was And Is " by Edward Heron Allen , and this what he said. " By a wrong arrangement of the sound post or base bar what are termed wolf-notes are produced , when present they may generally be cured by the proper adjustment of the bar or post ".
i like new harmony. check cello sites for how to determine where to place it.
If it is an after-length (between the bridge and tailpiece) issue, try moving a piece of blue tack around the string that matches your wolf pitch when you pizz on the wrong side of the bridge. Often it will be between Eb and F#. If that works, I would recommend a light mass eliminator first.
My back-up Ernst Heinrich Roth viola developed one after I removed a fine-tuner tailpiece. It was well remedied with a very light new harmony wolf eliminator tuned to match the wolf.
Oddly, a mute such as the Spector, Poly, or Finissima that grab the string can also tame wolf notes when well placed.
I have 2 Krentz "modulators" as they call them, instead of just saying wolf eliminator. I have been thru all the other wolf eliminators on violin, viola and cello, but each of them did only a little bit; the Krentz really does the job. If you can't find a cheaper remedy, get a Krentz. I think they have a money back guarantee, so you are at no risk! Best of luck!
Different strokes for different folks!
Can anyone recommend further in depth material on the causes of wolf notes ?
Google "wolf note on string instruments".
Ken, in a nutshell, the string moves the bridge, the bridge moves the top of the instrument, and then the top moves the bridge and the attached string. If the top moves enough, there will be two separate frequencies trying to vibrate the string: One at the natural resonance of the instrument top feeding back through the bridge, and the other from the finger stopping position. The poor string gets confused about which one to choose, so it goes back and forth between the two. ;-)
