Yamaha C6 bass strings

[Clyde Hollinger]

Friends,

I've been tuning a Yamaha C6 grand for the last five years, 6-month 
tunings and a complete Piano Life Saver system..  I don't know its age, 
since Pierce only goes to 1996, but it's newer than that.  I tuned it 
again today, and it sounds to me like some of the bass string windings 
are loose.  I didn't do anything about it for two reasons.  One, they 
haven't complained about it.  Two, I think I read on this forum at some 
time that Yamaha felt the strings shouldn't need twisting.

Does anyone remember any kind of discussion about this?  It seems to me 
that a piano of this caliber shouldn't be having this problem.  Or has 
it been a problem common in this model?  Your input is appreciated.

Regards,
