SCIENCE APPLIED TO SINGING

A retiarkable lecture was delivered at the Body Institute the other evening by M. Piitau ; a gentleman who has applied to the movements of the human voice the principles that have given to manklud tbe phonograph.

M, Piltau, having made the emission of the haujnu vjioe the subject of phyei.il glcal investigation, foand by ex* pertinent that the movements of the glottis during tho emission of sound, for from being volantury, were rtfljx movements, or, thnt tha vrca'e cords, like tbe tor.gue and the uvub, are governed by the resp-Titory movements, and rise and fall automatfotlly with the efforts of Inspiration and expiration.

M . Piltau bat devised delio »te apparatus to measure these efforts executed by the abdominal and thoracic mueo'ea, consisting principally m an indlarubber pad filed with air, fitting to the part required and attaohed by a belt or stays. These rubber pads communicate by means of Indiarubber tubes with hermetically closed drums, the outer o'osare being a membrane, which vibrate* to the slightest movement of the muscle beneath the pad. One end of a leveratyloa rests npon the membrane and the other corresponds with a dial plate, upon which its indications may easily be read, or they can be automatically recorded on a revolving cylinder oovered with lamp black. The apparatus for the larynx is slightly different ; the movement to be recorded being vertical, but the principle is the same.

In the experiments performed by M. Piltau the indications of the lever-points on the dials are made apparent, much am pllfied, by|meanaof the oxy-bydrogen light,

The Btudy of the movements of the abdomen and thorax daring respiration shows that singers posseßaiog good voices invariably, but unoonsofuusly, breathe In the same manner, whereas those with de feotive voices have altogether different methods of breathing, and on examining the relation that exists between the respiratory movement and that of the glottis, It iifouod that the slightest lowering of the diaphragm suffijoa to oloee the glottis.

Starting from these prem'ses, M. Plltau concludes aa follows : — That voice is the result of a shook and struggle between the inspirator, and expirator muscles; thit the point where this shook occurs determines the pitch of the note; that the larynx and the glottis do not form the note, bat simply modify it ; that, m fao', the note ia produced solely by the respiratory movements, which are under our control and can be governed and direoted at will. ;

Upon this theory the the inventor has basad a method of teaching by which the singer upon whom ihe apparatus baa been applied, being able to follow on the dialplate the movement of his larynx, caa correct that movement if necessary by modifying the respiratory movements of abdomen and throat.

Among those witnessed M. Piltau's experiment* at the Rudy Isatitute were Dr Faavel and the eminent composer M, Camilla Saint-Si 4 as.
