| In Delicate Perception the Ear Il MePs
Wonderful Than the Eye
The ear is a wonderful comprehen,
sive instrument As compared with
the eye il is vastly superior in extent
of the sensations it is capable of ex.
periencing. The eve possesses scarcely
an octave and . half OF sensations
whereas the average ear, as We know,
has range of six or seven, while more
AGATE ears have q compass of fully
eleven octaveS And then the ear 10 .
wonderfully accurate instrument and
capah BILE of approaching minute differ
ences that would be wholly impossible
in the case of the eye. According to
Dr. W. II. Stone, IAN architect or
draughtsman who, between two lines
neither parallel nor in one plane, made
an error Of calculation not exceeding
one-thirtieth would gain credit for un-
usual precision. But in the ear one
thirticth amounts to quarter OF
tone, and by ear one-forty fifth is easily
determined" A skillful pianoforte
tuner can do much more He is called
upon, for instance, to distinguish be
tween true and an equally tempered
fifth, where the difference is only 1-lo0
of tone, He should accordingly be
able to recognize at least 900 different
sounds in an octave. More than this
according to the Investigations of Prof
Mayer, it is possible, under specially
favorable conditions and for sounds
whose pitch is near that of CS, to dis
- -
do not differ from each other by more
than 1-l20 of 4 sem;-tone-
In the rapidity of its appreciation the
ear is remarkable. In q fraction of q
second it can accurately refer any note
to its place in the scale and can just as
easily and quickly separate from each
other several widely different notes.
According to recent investigations
the ear is capable of hearing a
sound when only two vibrations
are made. 1t should, therefore,
hear the middle notes of the piano
forte in the two or three hundredth
part of . second 1t requires more
time, however. for the ear TO distin-
guish the full characteristic of note.
To do this, according TO the expert
ments of Exner, Auerbach and Kohl
rauseh. from two to twenty vibrations
are necessary.
With proper training and practice
the organ of hearing can be rendered
remarkably sensitive and accurate.
There is rarely any physical defect in
the ear itself The defects ordinarily
noticed and spoken of are such as can
be easily remsdied by cultivation The
organ truly may never be able TO re.
tain the remarkable range of addition
we have spoken of above, il may never
become SO 'spprehensive and discrim-
inant" as the ear of Mozart, but its
delicacy can be increased and its gen.
eral appreciation OF musical sounds
wonderfully improved This is especi-
ally true IL the work of instruction Is
begun in childhood, when the organ of
hearing Is naturally most sensitive and
most readily susceptible of cultivation
In making experiments with rods and
tuning forks giving very accurate
sounds, have frequently been struck
with the very great difference in the
ability TO perceive such sounds as man
ifested by young and old person.
Even when the latter were trained
musicians, they were incapable OF
hearing some sounds that were quite
audible to children who had no musical
training whatever. This fact, like
many others that might be adduced, Is
a striking commentary on the neces-
sity OF beginning early the training o:
the Young, when eye and e2r-not &c
speak Of the other senses-are ever on
