The Melodette, or Automatic Piano,

[Illustration]

The most marvellous mechanical invention of the age. It will play any

tune that ever was written, in a melodious and pleasing manner.

Difficult and simple music produced in a masterly style, and it can be

played by a child as well as by a grown person, and will furnish music

for social gatherings of any description, playing hour after hour,

without any knowledge of music being required in the operation. The most

wonderful of all musical inventions; a machine which in a purely

mechanical manner produces any kind of music, Waltzes, Polkas, Marches,

&c., &c., without any practice or knowledge of music whatever; in this

respect far superior to any music-box, even though it costs many times

as much, for there is no limit whatever to the number of tunes it will

play. This instrument is on a somewhat similar principle to the

wonderful Phonograph, the perforations in a flexible strip producing the

effect. It has just been perfected (the accompanying cut showing it in

its improved form), and is having the largest sale ever obtained by a

musical instrument in the country. It has solid metal cases in imitation

of green bronze; the notes or bars (the music producers) are metal, on

same principle as a tuning-fork, which produce clear and most melodious

notes, and never get out of tune; the bars are struck by strikers, the

same as the wires are in a piano, only they work automatically instead

of by the fingers. The strip of prepared paper in which the tune is

stamped or perforated, is about 10 inches wide, and as it passes through

the rollers and over the keys the strikers spring through the

perforations in the paper and strike the right note; this is all done

automatically, without any assistance from the operator (except turning

the rollers), and the tune is played perfectly. It would be one of the

most appropriate presents to make anyone, especially where there is no

other musical instrument. Its execution is admirable, and its capacity

or capability almost unlimited. It is selling faster than any musical

instrument ever invented. The music is fine, and everybody delighted.

The regular retail price of the Melodette is only $5, including a

selection of popular tunes. Address, The Massachusetts Organ Co., 57
