more scraping, it can sometimes be sharpened by bending it up and
down a few times, which has a tendency to put temper in the metal.
Some reeds are curved at the point purposely to secure a certain
voice. Do not interfere with the proper curvature when tuning. In
tuning organs, the same system and general instruction given for piano
tuning will apply; however, it is rarely, if ever, necessary to give
an organ as thorough tuning as you would a piano. It is a very tedious
job where you have to draw each reed, apply the proper method, insert
it and try the result, thus cutting and trying each one perhaps
several times before getting the desired result. In factories devices
are used which render the operation very much easier.

One thing you should know is, that organs are not tempered as finely
as pianos, nor is there the pains taken to secure perfect unisons. In
fact, you can hardly find a perfect unison in an organ of modern make,
much less, a correct temperament. Finding a tone that is so far out as
to be very disagreeable, adjust it between the octave below and the
octave above, try it in the proper chords and equalize it in the best
possible way; but it is not often you will be able to tune it to
absolute precision with its octaves. It is thought by many that a
slight deviation from correct unisons, sufficient to give a series of
waves, gives the organ a more mellow voice and consequently a more
musical (?) tone; and while we do not agree with any such proposition,
it makes the tuner's work less exacting.

We feel that an apology is in order for not giving illustrations of
the action of the organ, but if the student will study this lesson in
connection with the instrument itself, we believe he will have no
trouble in learning all about its mechanical action and its demands
upon the tuner.

LESSON XVII.

~CONCLUDING PROFESSIONAL HINTS.~

Peculiar incidents occur in the experience of the piano tuner, some of
which have
