Trent:

It sounds to me like you have the temperament strip too close to the termination point.  That will allow a lot of bleed through.  Move the temperament strip down close to the hammer line and it will dampen the outside strings better.

>Hello all,

>I have just begun learning to tune.  A few weeks ago I did my first complete tuning on a

>twice, because the bass and treble ends didn't sound so good the first time.  This was all

>Anyway, getting to the point, this gave me some confidence, so last week I decided to

>This piano is much harder for me to tune.  I am not sure why.  Maybe it is partly

>so I never got to compare the effect of the brightness on how hard it was to tune the

>When I say the M&H is much harder to tune, I mean just setting the temperament so

>The one thing I DO notice for sure when I'm trying to tune the Mason & Hamlin 
>upright, that makes it difficult for me, is that it is really hard to hear JUST the 
>undamped middle strings beating together.  Over and over, I was going back and forth 
>with notes I just couldn't seem to align decisively, and which seemed like they were 
>contradicting themselves, only to find out that it was one of the other, presumably 
>damped, strings of the unison that was causing the muddle.  (A lot of the time I was just 
>trying to make fifths beatless (at 3:2, I think) and the like, because I was going to tune it 
>aurally to Kirnberger II, and then re-tune it to ET when I learn enough to do so aurally.  
>The B&L I had tuned to Young's 1899, setting the temperament initially with a $35 
>Seiko electronic tuner, just doing a couple adjustments by ear.)

>On the Bush & Lane, I'd noticed this interference from the damped outside strings a few 
>times, too, but it only had an effect for the first fraction of a second or so, then 
>presumably the temperament strip killed the interference.  But on the Mason & Hamlin, 
>the interference from the outside strings seemed to last a couple seconds or so.  Plus, it 
>seems like maybe it actually influences the middle string, and it seems to make the last 
>steps of zero-ing in ambiguous.  

>So on the Mason & Hamlin, I found myself using the rubber wedges, four at a time, to 
>eliminate all this extraneous noise from the outside strings.

>I was wondering if anyone else finds it difficult to adequately damp the outside strings 
>with a felt temperament strip.  Or is my technique wrong, either the way I'm listening or 
>the way I'm using the strip, although I can't see too many ways to drastically improve 
>how I put it in.  Is noise from the outside strings normal, and you're supposed to learn to 
>work around it?  Or maybe I just have a cheap or incorrect type of temperament strip.  
>I noticed that the one that came in the Randy Potter materials seemed to have a high 
>synthetic content.  Maybe it would work better, but something happened to it 
>(involving it's being called to service in another musical instrument), so I've been using a 
>feltier/woolier one that I got in a box of miscellaneous used piano stuff, so I don't know 
>much about it.  It doesn't seem to fit too loosely or anything though.  

>Even when I was tuning the Bush & Lane, getting the muted strings to be muted enough 
>to hear more clearly was a recurrent concern as I worked (but not as much so on that 
>piano).  

>Basically, I'm wondering if being bothered by this is just some kind of beginner's thing.  
>Or is there really a problem with how I'm muting the strings that I can readily improve 
>with the right materials or techniques?  Or it is neither, and it bothers everyone 
>sometimes, but you just have to do your best with it?

>I should mention that because I've been doing a lot of temperament changing and 
>pitch-raising type things, the three strings of the unisons are often pretty far off from 
>each other, more than normal, so maybe that has something to do with this.

>What do you think I should try next?

>Thanks for any help and best regards,
