false notes-
problem with larsens?
I play a Gliga cello, it's about a year old and I've used Jarger
medium strings on it so far. For an exam I wanted a better sound, so
put Larsens on.
The G sounded weird straight away, like a
twangy guitar string, so I sent that back to the distributor and put
the old jarger G back on.
Meanwhile, the larsen D string,
which had initially sounded good,
started to "choke up", giving
false, strangled harmonic type notes, especially on F#.
The
distributor sent me a solo quality larsen G, but that started doing
the same thing as the D string. It was unplayable within 24
hours.
Is this likely to be a problem with my cello, the
strings, or the combination of string & cello?

Re: false notes-

I suggest that before you give up on your cello's setup, you make
sure the problem is not due to collection of rosin on the strings.
Wipe of the strings (hard) with a cloth that makes an awful squeak,
possibly even use your thumbnail to take of the top
rosin.
When I was testing bows in a shop I found rosin
collecting on the strings very rapidy, from the heavily rosined bows
I tested, and this would spoil the sound very quickly - even on some
good instruments and good bows. Also, bearing down too hard on the
bow can hasten the effect.
Some rosin are more resistant to
causing this problem and some strings seem more immune to sound
effects of rosin buildup or even rosin buildup itself.
I find
it somewhat interesting that you are finding an F# resonance, since
this is a common wolf tone (although more often on G and C strings
than on D). It would not be amazing for this to occur as the string
tension stabilized to some value that will support the resonance. Do
you also have the F# resonance on the G string, just below the
octave harmonic?
There are other false notes that some cellos
will sound (especially higher up) that can be eliminated by changing
string brand, using proper bowing angle, speed, or pressure,
adjusting hair tension, or by using a different bow.

Re: false notes-

It sounds like a wolf note, perhaps exacerbated by the rosin build
up Andrew mentioned. Sometimes changing the tension of the strings
you are using can cause this, but I don't think changing to a Larsen
from a Jargar would make this difference, as they are very similar
in tension.
And yes, the Larsen G and C strijngs can feel
very lightweight - they can get a very nice sound, just not a lot of
it.

false notes
continued
There was no corresponding wolf note on the G string, so I don't
think it was a wolf. I think my wolf is between F# and natural.
Plus, the G string started doing the same thing around the B in 1st
position within a couple of hours of it being fitted, while the D
took about 3 days to go off.
Interesting what you said about
over-rosining Andrew, I followed your previous postings about rosin,
and came to the conclusion that I do use too much. I have to clean
my strings with that awful squeak most nights when I finish playing,
and the rosin I use is a cheap & nasty variety. I intend
following up the Liebenzeller gold when I can afford it.
I
also tend to bow heavily, another subject altogether.
The
A&C larsens have continued to behave normally, weeks after
fitting, I would've thought that over-rosining or heavy bowing
would've affected them the same as the D&G???

took a while replying, but I'm in a different time zone (Australia)
and use the internet at the local library every couple of
days)
