RCA Victor Announces New Type
Of Three-Speed Record Player
A new and improved type of
"Victrola" three-speed record player,
designed to provide in a single turn-
table reproduction from records of all
three established revolving speeds, has
been announced by the RCA Victor
rpm discs.
Completely automatic, the new rec-
ord player: plays up to 14 45-rpm
records at one loading; up to ten 12-
inch or twelve 10-inch standard or
long-playing discs at one loading; up
to ten intermixed sizes of 78-rpm, or
THE NEW. 3 SPEED AUTOMATIC RCA RECORD PLAYER ATTACHMENT
AND THE NEW 3 SPEED SELF CONTAINED UNIT.
Division of the Radio Corporation of
America.
Under development for more than a
year, the new instrument marks the in-
troduction of RCA Victor's first three-
speed record-playing system, it was dis-
closed by H. G. Baker, vice president
in charge of the company's Home "In-
strument Department. Four models in-
corporating the new record player were
scheduled to be shipped to distributors
early in May.
Heart of the new instrument is a
novel slip-on 45-rpm spindle which
houses the automatic record-changing
mechanism of the 45-rpm system. The
larger slip-on spindle fits over the
permanent 73/331^-rpm spindle and
converts the new record player into an
authentic 45-rpm instrument, with all
the engineering advantages and per-
formance features of the "45" system.
With the slip-on spindle removed, the
instrument, at the twist of a selector
knob, will play either 78-rpm or 331/3-
the same number of 331/^-rpm records
of intermixed sizes. It stops auto-
matically after playing last record of
any of the three speeds; provides two
separate pick-up points in a single tone
arm. one for playing 78-rpm discs and
another for the 45-rpm and 33 1 /3-rpm
records and eliminates the need for
record inserts.
The new all-speed "Victrola" instru-
ments include a record-player attach-
ment (Model 2JS1), which can be con-
nected to any radio, phonograph, or
television set. Other models are a self-
contained phonograph (Model 2ES3)
with a built-in speaker and amplifying
system, a self-contained portable unit
(Model 2ES38) housed in a luggage-
type carrying case, and a three-speed
table model Victrola radio-phonograph
(Model 2US7).
For 45-rpm, the operator need only
turn the speed-selector knob to the
proper speed. For either 78-rpm or
331/j-rpm, the only additional step re-
quired is to lift the large spindle off

PRACTICAL PIANO TUNING
By ALEXANDER HART
Formerly with Steinway & Sons Tuning Department, Instructor in
Piano Tuning, Teachers College, Columbia University, N. Y.
Registered Member of the
National Association of Piano Tuners
Notes of Interest on Tuning
HE keyboard charts used in this
article are to help the ambitions
and conscientious tuner to advance
himself by the way of analyzing the
chords quality and work out a better
solution by using four augmented
chords as exhibited on the charts.
The tuner should be acutely con-
scious of tone relations in order that
his chords may sound extremely musi-
cal rather than mathematical.
Each degree of the scale has its own
individual flavor according to its func-
tion in tonality. This procedure, how-
ever, is a matter of preference, for
many tuners have their own formula
worked out, and others again who
never seem to be quite satisfied with
their temperament. Perfection is the
aim. a good slogan to go by.
A major performance in the art of
tuning pianos calls for plenty of study
and practice.
How to understand the charts is ex-
plained by following the rules. Pro-
ceed slowly, and do not deviate if pos-
sible from the method until you have
gained a little insight as to what it's
all about.
First, note K.B.C. stands for charts
—"Aug" means the fifth tone has been
augmented. That is. raised a half-tone.
Defining the practical use of the
augmented fifth, it is also a minor
sixth, being raised another halftone, it
becomes a major sixth, like the one
employed K.B.C.-l, G and E. It also
takes two major thirds to be an "Aug"
fifth, and its practical use in finding
the enharmonic as seen on K.B.C.-2-A b
Aug. Counting 9 halftones each way,
you can see that G# is on the right
side of E major and A b is on the left
side of C major—Middle "C" taken
as a starting point. That at once gives
you another tonic A b G#. Incidentally,
then you can proceed to tune the other
intervals as E below A b and octave
below Middle C. Then you have the
inversions for Key of C Major.
From A b is a new root of a chord
made up of three tones built in thirds
24
MODEL C
CHORDS CAN BE CLOSELY MATCHED, THUS FORMING A GOOD BRIDGE BETWEEN
THE AUGMENTED CHORDS. THE TUNING CAN BE CHECKED CLOSELY AT EVERY
POINT AND THE CONSTANT ENHARMONIC CHECKS WILL NOT ALLOW THE ERRORS
OF JUDGMENT TO ACCUMULATE
—the only difference in the "Aug"
chord is that it has no minor. You
can see it on the K.B.C.
Explanation of the Triad
1—The triad is a chord made up of
three tones built in thirds.
2—The root of the triad is the tone
from which the chord is built.
3—The third of the triad is a third
from the root.
4—The fifth of the triad is a fifth
from the root.
5—Triads may be built on each tone
of the scale.
