I was planning on a looking at a local Yamaha G5 and have a question. This piano is all original, however I'm not sure if the bass strings should have that twist on them? I looked online and found a few other pics showing a similar twist in the string. Is this normal?

I am not sure what twist you are talking about, but it is common for bass strings to be twisted when they are installed.

Are you talking about what might be called swaging at the ends of the wound portions, by the bridge?

I don’t know if it’s original to the piano, but I have seen that done by some European piano manufacturers...on pianos with beautifully matched bass bichords and on ones with poorly matched bichords.


I agree with Keith.

Apparently, some are and some are not.

I just took this pic of the bass strings on my Yamaha C7, which have had a few (more than a few:-) replaced. It had a couple of broken bass bichord strings (on different notes) when I bought it. I'm thinking the ones with the twists are the original bass strings. The replacements I measured and ordered from Aldridge piano string Co in Tennessee.

(*the date on the pic is wrong.. I just took the pics a few minutes ago; didn't feel like setting the date on my digital camera).

Hope this helps...

That absolutely helps! Thanks a bunch. I wasn't sure if something weird was going on with the bass strings on the one I'm going to look at.

That is just the way they anchor the winding when they wrap the strings.

At Mapes they call the ones with the twist at the swage; "Reverse Whips".

What's are the advantages/disadvantages between the 2 types of anchors on bass string windings? Durabability, tonality, etc.?

I'm just guessing here, but I'd think the strings with extra winding twists might be more tightly wound on the end and less likely for the winding termination to become loose and cause a rattle; that might mean longer durability over time (?). I doubt the extra windings would cause a difference in tone, but I could be wrong.

On my Yamaha C7 I can't tell a difference, tone wise, between the bass bichord notes with the extra windings on the end and the ones without. When I installed the new bass strings (without the extra windings on the end), they did sound a bit sharper and clearer than the older ones, initially. But now they all sound pretty much about the same.

Also, when replacing wound bichord strings, always replace both... never just one of the pair. I did, however, learn a valuable lesson about installing copper wound bass strings... never handle the strings with your bare hands (no matter how clean your hands). smile
