Speaking of Steinway grand sizes

[Richard Brekne]

That is a very kind gesture and I thank you kindly for it. I'll send it 
along to Hellerman with my other data.  You did catch that this turns 
out to be an L scale yes ?

Cheers and thanks

    Quite so!  I have made many sets of strings for the miniature and not
    once copied the original scale, which takes the tension far too high
    most of the way through the bichords -- for example note 26 has a
    0.55 cover on a 15.5 core, giving 84% of UTS, where we set 70% as the
    limit.  I have all the details for the original factory scale and it
    is not impressive.  In fact very few of Steinway's bass scales are
    acceptable.

    One thing I would advise against for the Miniature is the use of any
    double-covered strings to replace the low single-covered strings.  I
    have done various experiments expecting to improve the quality of the
    tone in these strings, but the structure of the piano seems to
    respond best to single-covered strings similar to the original scale,
    which are able to shake the piano in a rather unusual way.

    For what it's worth, here is the scale we use:
