The British army is bound by His Majesty's Rules and Regulations to play at the Philharmonic pitch, and a fork tuned to a' 452.5 in 1890 is preserved as the standard for the Military Training School at Kneller Hall.
A frequent combination was flute, violin and harpsichord (very probably with a violoncello doubling the bass), and in more than one case the violin was partly tuned lower to soften its tone.
Stein tuned Mozart's piano to a fork a' 421.6, and the Broadwood pianos used at the London Philharmonic Society in its first concerts (1813) were tuned to a fork c 2 506.8, which gives a mean tone a' 423.7.
Johann Heinrich Scheibler (1777-1838) tuned two forks to an exact octave, and then prepared a number of others dividing the octave into such small steps that the beats between each and the next could be counted easily.
Without looking at anyone, "Uncle" blew the dust off it and, tapping the case with his bony fingers, tuned the guitar and settled himself in his armchair.
In the Lower Harz, as in Switzerland, the cows, which carry bells harmoniously tuned, are driven up into the heights in early summer, returning to the sheltered regions in late autumn.
Dean tuned Fred to the off position until his stepfather floated back to reality and continued.
He was so tuned in to Elisabeth's voice, that just by scanning a piece of music, he knew where to change the composition to compliment her, and where to back off to let her shine.
Schlick goes on to say the organ is to be suited to the choir and properly tuned for singing, that the singer may not be forced to sing too high or too low and the organist have to play chromatics, which is not handy for every one.
He also devised a " call " or arrangement for actuating an ordinary electric bell by the accumulated effect of the properly tuned inductive impulses falling on the secondary circuit.
When oscillations are excited in this last circuit they communicate them to the antenna provided this last circuit is tuned or syntonized to the closed circuit, and the radiating antenna has thus a large store of energy to draw upon and can therefore radiate prolonged trains of electric waves.
This receiver therefore, like the transmitter, consists of an open and a closed electric oscillation circuit inductively connected together; also the two circuits of the receiver must be syntonized or tuned both to each other and to those of the transmitter.'
Marconi exhibited in October 1900 this apparatus in action, and showed that two or more receivers of different tunes could be connected to the same antenna and made to respond separately and simultaneously to the action of separate but tuned transmitters.
When the methods for effecting this had been worked out practically it finally led to the inventions of Slaby, Braun and others being united into a system called the Telefunken system, which, as regards the transmitter, consisted in forming a closed oscillation circuit comprising a condenser, spark gap and inductance which at one point was attached either directly or through a condenser to the earth or to an equivalent balancing capacity, and at some other point to a suitably tuned antenna.
A compromise has to be made, and the note has to be tuned so as to make the compromise as little unsatisfactory as possible.
V., on public buildings, has a preface on the theories of Pythagoras, &c. Its twelve chapters treat - (t) of fora and basilicae, with a description of his own basilica at Fanum; (2) of the adjuncts of a forum (aerarium, prison and curia); (3) of theatres, their site and construction; (4) of laws of harmonics; (5) of the arrangement of tuned bronze vases in theatres for acoustic purposes; (6) of Roman theatres; (7) of Greek theatres; (8) of the selection of sites of theatres according to acoustic principles; (9) of porticus and covered walks; (to) of baths, their floors, hypocausts, the construction and use of various parts; (ii) of palaestrae, xysti and other Greek buildings for the exercise of athletes; (12) of harbours and quays.
But a cardboard tube closed at one end, with the open end near the ear, will often suffice, and it may be tuned by more or less covering up the open end.
