to study the best methods of loading bass again, anything that could be done to avoid
strings, the system of spinning which is uni-
versally in use should for so long have remained
without improvement. I do not mean to say
that bass string making, as now practiced, is
not ingenious and commonly satisfactory. What
1 do mean to say is that bass strings, covered
strings, give more trouble than strings not
covered, and that part at least of the defects
which are to be found in them may be traced
to current methods of spinning. Whether a
better practical method can be evolved need
hardly be a matter of question. What is far
more to the point is how much the industry
itself may be really interested in anything bet-
ter, especially if it should cost a little more.
Changes to Come
Yet sooner or later we must come to changes
because the conditions of piano making are
rapidly changing and are calling for improve-
ment in this as in other features. The short
stiff bass strings of small pianos are not sat-
isfactory in their tone-making function, and
it is certain that some change in the method
of making them will be thought out. Several
possibilities present themselves. Readers of
Siegfried Hansing will remember that in his
treatise on the acoustic relations of the piano
this eminent German piano maker spoke of a
so-called "compound" wire patented by one
Subers, which was heard of some thirty years
ago. The strings made by this process com-
prised three strands of wire plaited together,
and the inventor claimed for them various vir-
tues, which, however, did not appeal to Mr.
Hansing. I have never been fortunate enough
to see, hear or study wire made by the Subers
process, which apparently failed to capture the
imagination of the piano trade, but have often
thought that something might be done by com-
bining two or more core wires in such a fashion.
Such wires would, of course, vibrate as one, if
all were of the same length. If, however, the
plaiting process merely wrapped two wires
around a third, the third would be the vibrator
and the others merely loads, with the disad-
vantage of being themselves highly vibratory.
On the other hand, a careful plaiting of three
wires of equal diameter would give three times
the weight of one wire, while each would, or
should, vibrate as one wire, not in frequency but
in pattern. Thus, three No. 13 wires plaited
together would weigh in grains per inch a
very little more than one strand of No. 23^2
and a very little less than one strand of No.
24 wire. And if combinations of wires of dif-
ferent diameters could be made, various ar-
rangements of loading might be worked out.
An Alternative
I am not suggesting that here is an imme-
diately practical improvement, or even that it
really is an improvement. I merely point out
that an alternative to the present method does
exist and that doubtless still others can be
brought into view. Thus, it would probably
be possible to shrink upon a core wire a tube
of copper or soft steel so that there should
be no danger of that slippage which is so

the present irritating and uncertain practice of
swagmg the core wire at each end in order to
clamp the covering wires would certainly come
as a boon and a blessing to every maker of
brass strings. Perhaps not everyone is aware
that it is necessary to treat the core wire used
for bass strings somewhat specially in order
that it may stand the swaging and also the
severe twisting which it undergoes when the
eye is put on it for the hitch pin.
A Fine Adaptation
Bass string practice indeed represents one of
the best adaptations, even as it stands, of means
to an end, when we consider how very little
encouragement the makers of either the wire
or the finished strings have had from the
manufacturers of pianos. Some day the piano
industry will come to realize this, and I for
one should be the last to bring facile and
superficial charges or to make aimless criticisms
of a difficult piece of work which on the whole
has fulfilled its purpose very well. On the
other hand, the time is ripe for the study and
analysis of this, as of other matters, and I
am violating no secrets when I say that others
besides myself are to be provided, within the
near future, with facilities for entering into
very detailed studies along these and related
lines. And of all that much more is likely to
come out in these columns.
