THE EI.ECTRlC PIANO.

Dir Thomas Davenport Of Salisbury (yt) who claims to
be the 6rs in the world who turned wheel by neans
of has succeeded after several years OF
application to the subject, in vibrating musical wires oF
means Of the power The perpetual and hitherto in
durable defect of the forte is the mpuve and evanes
nature Of its Tone and though great improvements have
been made upon and various devices have been elaborated
aned vibration is still an inherent in that beautiful
instrument There is something foreign TO the true idea and
influence of music in that perpetuaiy tnpse and
the notes which II produced have not the trait OF
Linked sweetness long Gra,en QUIZ
which the demands essential attribute 10 melody.
The oltan attachment excited high hopes for time that
would afford relief against this inherent defect OF the P
ano but this invention has been found very unsatisfactory
and imperfect in practice Mr. Davenport proposes
submit to the public invention not to exc out the
imperfecons of this noble instrument accompan
en but remedy the deficiency directly by doing what
the wit of effected beforenamey by causing the
musical chord continue cqusbe and free filtration for
any desirable length of time Whether he has accomplished
this object in practicable remains 10 be seen here
after.
The simple but vastly important fact of the science of cleo
tronagnetsm is iron being encirced by
Of electricity, becomes instantly and intensely magnet
c and again becomes instantly destitute OF magnetic pro-
perties on the suspension OF the electric currents The pro-
bem with which Mr. Davenport has grapped and which he
has solrcd is-rst whether this twofod transition be
perfectly effected rapidly musical chord will yeratc
(say for example, five hundred times second and second
y, whether this rapid alteration Of attraction and absence
attraction can be made 10 concur exactly with the vibrations
of The chord sustain those vibrations. This
have said, Mr.. Davenport has tumphspty accomplished
We have seen rude under his drc
HONS similar in form oan harp and furnished with
three wires which continue vihat under the influence Of
agnetic with cear and full for any desired
length Of tie after the first impulse Is impaired SO far
demonstrated shall be found possible as the
inventor enterains doub TO apply this the piano in
neat practicable Manner it ia saying little that Mr..
Davenport has made the important improvement in
musical instruments of the present age. Vermont Hhg
