The G, fifth above, should vibrate
384, but in the tempered scale it beats but 383.57, almost half a
vibration flat. This would give nearly 2 beats in 3 seconds.

These figures simply represent to the eye the ratios of these sounds,
and it is not supposed that a tuner is to attain to such a degree of
accuracy, but he should strive to arrive as near it as possible.

It is well for the student to practice temperament setting and regular
tuning now if he can do so. After getting a good temperament, proceed
to tune by octaves upward, always testing the tone tuned as a fifth
and third until his ear becomes sufficiently true on the octave that
testing otherwise is unnecessary. Tune the overstrung bass last and
your work is finished. If your first efforts are at all satisfactory
you should be greatly encouraged and feel assured that accuracy will
reward continued practice.

QUESTIONS ON LESSON X.

1. What is meant by the term "equal temperament"?

2. What is meant by the term "unequal temperament"?

3. Webster defines the term "temperament" thus: "A system of
compromises in the tuning of pianofortes, organs, etc." Explain
fully what these compromises are.

4. In testing chords to ascertain if temperament is correct, what
is the main thing to listen for as a guide?

5. In what three chords would you try the tone A, in testing your
temperament?

6. With what results have you demonstrated the experiments in this
and the previous lesson?

LESSON XI.

~THE TECHNIQUE OR MODUS OPERANDI OF PIANO TUNING.~

At this juncture, it is thought prudent to defer the discussion of
scale building and detail some of the requirements connected with the
technical operations of tuning. We do this here because some students
are, at this stage, beginning to tune and unless instructed in these
things will take hold of the work in an unfavorable way and, perhaps,
form habits that will be hard to break. Especially is this so in the
matter of setting the mutes or wedges. As to our discussion of scale
building, we shall take that up again, that you may be more thoroughly
informed on that subject.

Some mechanics do more work in a given time than others, do it as well
or better, and with less exertion. This is because they have method or
system in their work so that there are no movements lost. Every
motion is made to count for the advancement of the cause. Others go
about things in a r
