as to mark them. Certain pins are marked to guide the tuner in placing
his hammer. The way we have always marked them is as follows:

Mark both pins of each pair of C strings with white crayon. Mark only
one pin of each pair of G's. Knowing the intervals of the other keys
from the marked ones, you can easily calculate correctly, upon which
pin to set your hammer to tune any string desired. For instance, if
you are striking D♯, next above middle C, you calculate that, as D♯ is
the third chromatic interval from middle C, you are to set the hammer
on one or the other of the pins belonging to the third pair to the
right of the pair marked as middle C. B would be first pair to the
left, F♯ would be first pair to the left of the marked G, and so on.
It is usually necessary to mark only those pairs near the middle of
the piano, but we advise the beginner to mark throughout the scale, as
by so doing he may avoid breaking a string occasionally by pulling on
some other than the one he is sounding. This will occur in your early
practice if you do not use caution. And for safety, some tuners always
mark throughout.


QUESTIONS ON LESSON XI.

1. By what means is the tuner enabled to make the strings draw
through the bridges and equalize the tension throughout their
entire length?

2. State conditions that may result from a tuning pin's not being
properly set.

3. In this system of muting, state definitely which string is
