HARPSICHORD
A keyed musical instrument,
formerly in extensive use, but
now little known. In shape it
was exactly like a grand
pianoforte, to which its
internal arrangements were also
similar. The sound from the
strings was produced by a small
piece of crow-quill, or a piece
of hard leather, which projected
out of a slip of wood, called
the jack, that stood upright
between the strings, and was
pushed upward by the key till
the quill, or leather, twitched
the string , causing a brilliant
but somewhat harsh sound,
deficient of any means of
modification in respect to
loudness or softness. Specimens
of the harpsichord, although now
becoming quite rare, are still
to be found in good
preservation, but rather as
articles of virtue or curiosity
than as useful musical
instruments. Many Italian and
Dutch harpsichords were highly
ornamented by the most eminent
artists with valuable oil
paintings on the inside of the
lid. The date of the invention
of the harpsichord is uncertain.
Before the fifteenth century
there is no trace of its
existence. It was introduced
into England early in the
seventeenth century. In the
eighteenth century Kirkman, and
later Broadwood and Schudi, were
the famous makers in London.
After the invention of the
pianoforte the harpsichord and
all instruments of the same
kind, such as the spinet, were
in time entirely superseded. The
harpsichord shown in the
accompanying illustration was
presented to Nelly Custis by
George Washington. It was made
in London, is eight feet long,
three and a half feet wide, and
has two banks of 120 keys.

INTONATION
In music, the production of tone
either by an instrument or by
the voice. It is of no
importance in keyed instruments
like the piano or organ, as the
performer can only strike the
proper key and is powerless if
the isntrument is not in tune.
But the matter of intonation is
of utmost importance in the
voice and all string and wind
instruments. Only a person
having a finely trained ear is
able to produce proper
intonation. Hence we speak of
pure and false intonation.

JANKO KEYBOARD
A keyboard for the pianoforte
invented by Paul von Janko in
1882. This was introduced to the
English public in 1888, and in
New York in October, 1890. The
Janko keyboard consists of six
rows or banks of keys, placed in
a semicircle and presenting a
fan-like appearance. Each note
has three different keys, one
lower than the other and
attached to a key-lever, so that
each key may be struck in three
different rows. Six parallel
rows of whole-tone intervals are
thus produced. The keyboard
slants, the keys are rounded on
both sides, and the sharps and
flats are distinguished by black
bands. A freer use of the
fingers is claimed than with the
accepted keyboard. By reason of
the many rows, the hand can
maintain its natural position
with the long fingers on the
upper notes and the shorter ones
on the lower. All scales and
chords have uniform fingering,
the relative position being the
same in all keys, and the only
necessary change is to raise or
lower the entire hand. The
octave is brought within the
stretch of the sixth on the
ordinary keyboard, and half
tones bay be played legato with
one finger. The new keyboard can
be adapted to any pianoforte,
grand, upright, or square,
without harm to the instrument.
Chromatic scales in thirds,
sixths and octaves can be
executed with as much facility
as the ordinary scale on the
ordinary pianoforte, because one
performer can produce effects
that now are obtainable only in
four-hand playing.
K
KEYBOARD
A frame containing a set of
keys, placed in the front part
of the pianoforte or organ. The
word is also applied to the
keys, or digitals, taken
collectively. The natural keys
are of wood covered with white
ivory, and the raised keys,
touched to produce sharps and
flats, are blocks of ebony or
other hard black wood. The
influence of the keyboard upon
the development of modern music
is important. The earliest
keyboard of which we have record
was that of the jydraulic or
water organ, a Greek invention
of the second century. In this
the keys, eighteen in number,
were all level. Strange to say,
the principle oof the balanced
key, which had to be
rediscovered in the seventeenth
century, was then well known.
Our modern chromatic keyboard
was in use as early as 1361,
though the keys were so large
that they had to be struck with
the fist. Their width was,
however, gradually lessened, and
in the spinet made by Pasi, of
Modena, in 1490 (the earliest
instrument of this class), and
in the organ of Saint Blaise at
Brunswick (1499), the compass
was approximately that of our
present keyboard. In most of the
early instruments the natural
notes are black and the sharps
and flats white. Several
attempts have been made to
reform the keyboard. The
principal objection to all
rearrangements is the fact that
there is a mass of beautiful
music, written for the modern
pianoforte, which could not be
adapted to an improved
instrument.

M
MODULATION
The process of changing from one
key to another within the same
composition. In a movement of
even the smallest dimensions
monotony would result if the
composer should confine himself
strictly to one key. There are
two kinds of modulations,
passing and final. Passing
modulation introduces chords
belonging to other keys only
incidentally and soon returns to
the original key.But when a
piece modulates so that the
original key is abandoned and a
new key takes its place, the
modulation is final. In the
sonata-form (see SONATA) the
first development of the
principal subject confines
itself only to passing
modulations. A final modulation
occurs at the entrance of the
secondary subject (generally to
the dominant key). The second or
development section is concerned
entirely with passing
modulation. But even here the
choice of keys is not arbitrary.
However, no rules can be given;
the artistic and aesthetic
instinct of the composer is the
sole guide. According to the
theory of the present day, all
modulation is regarded in its
relation to the principal key of
the piece, and in a wider sense,
all keys are but steps within
the unlimited domain of
tonality. Older composers are
very sparing and careful in the
use of modulation, but those of
the nineteenth century
(especially Wagner, Schumann,
Chopin) practically removed all
barriers. The means of
modulation are various and
cannot be discussed in an
article like the present. The
most frequent expedient is the
different interpretations put
upon the same chord. Thus the
chord c,e,g may be conceived as
tonic of C, dominant of F,
sub-dominant of G, etc., and
consequently can be used to
modulate at once to those keys.
In modern music the chord of the
diminished seventh plays an
important part in modulation.
Thus C#, e, g,bb
leads into D minor; the same
chord conceived as e, g, bb,db
into F minor; as g, bb,
db, fb
to A flat minor; as a#, c#, e, g
into B minor, etc. The principal
works on modulation are: Draseke,
Anweisung zum kunstgerechten
Modulieren (Freienwalde, 1876);
Riemann, Harmonie und
Modulationslehre (Leipzig,
1900); Jadassohn, Die Kunst zu
modulieren (Leipzig, 1890).
MANUAL
The keyboard of an organ played
by the hands, in
contradistinction to the pedal,
played by the feet. The number
of manuals varies from two to
four according to the size of
the organ. In older French
organs even five manuals are
found. The names of the
different manuals are: (1) Great
organ; (2) choir-manual; (3)
swell-manual; (4) solo-manual;
(5) echo-manual. Each manual
really is a separate organ in
itself, having its own set of
pipes and stops. By means of
couplers any or all of the
manuals can be connected, so
that by striking a note on one
manual the same note sounds on
all the other manuals that are
coupled. The usual compass of
manuals is four octaves and a
fifth, C-g.
METRONOME
A small machine for indicating
the correct time or speed at
which a musical composition
should be played. It was
invented in 1816, and consists
of a pendulum, actuated by
clockwork, which swings in front
of a graduated scale. To the
upper part of the pendulum-rod
is attached a movable weight
which can be set at any figure
indicated by the scale. The
figure 60 means that when the
weight is set there the pendulum
swings 60 times a minute. Thus
it beats exact seconds. When set
at 120 it beats half seconds.
The metronome indication appears
always at the beginning of a
composition. M.M. (Malzel's
metronome, from its reputed
inventor, Malzel) By means of
the metronome the composer is
enabled to give the minutest
directions in respect to the
tempo, for the old terms
allegro, andante, presto, etc.,
can only serve as approximate
indications, leaving much to the
temperament of the individual
performer. The metronome is of
the greatest value and is much
used today in training beginners
to play strictly in time.
