able for other things. Where pupils have a
hard time getting hold of the expression of a
passage, as a last resort, they can play right
with the Duo-Art at a moderate tempo and thus
get an absolutely correct idea of every detail
of the artist's interpretation.
However, I
would not encourage a too slavish imitation of
the artist and at times original departures are
made."
"Hut what effect does the perfect playing of
the Duo-Art have on pupils? Does it not dis-
courage them and make them feel that they can
never attain a like ability?"
"On the contrary, I have not had a single
case of this sort. In listening to the Duo-Art
you come after a time to feel that it is not a
mechanism you are listening to but a person, and
such is really the case. Rudolph Ganz says,
'Whoever criticizes a Duo-Art record of my
playing criticizes my playing,' or words to that
effect. It is this personal and human element
in the Duo-Art that prevents discouragement on
the part of the pupils, for they argue that what
others have done they can do. Many times the
hearing of the records is a great encouragement,
as they realize that their playing is coming close
to the standards set by the world's greatest
artists. This means of comparison of their own
playing with such standards prevents undue
modesty as well as undue conceit. In our re-
citals at the conservatory we are following a
plan of having a pupil's playing of a piece fol-
lowed immediately by the Duo-Art record of the
same piece so that the audience may appreciate
how nearly the pupil has attained the standard
of the artist. Many times surprising results are
obtained. No, if the hearing of the Duo-Art
records had a discouraging and demoralizing ef-
fect upon the pupihs, they would not ask so per-
sistently to be given pieces which have been
recorded on the Duo-Art. They much prefer
them to ordinary pieces."

DEVICE FOR HAMMER CONTROL
George Q. Chase Secures Rights to Patent
Granted on Recent Invention
WASHINGTON, D. C, October 7.—Patent No.
1,278,807 was last week granted to Edward
Arthur Tappe, Los Angeles, Cal., for a player-
piano, which he has assigned to George Q.
Chase, San Francisco, Cal.
The invention relates to player-pianos in
which the hammers are normally held in reduced
or half stroke position by the use of a hammer
rail made in movable sections controlled by
pneumatic actuating devices for moving any
one of the hammer rail sections into position
for holding the corresponding hammer in full
stroke position.
The object of the invention is to provide a
new and improved player-piano having ham-
mer controlling devices which are simple and
durable in construction and which can be read-
ily applied to a grand piano player or to an
upright piano player as now generally con-
structed.
