Abstract
Abstract A programmed system for polytempi music and dance has a mechanically operated timer with means for operating a group of electrical circuits to produce audio and visual signals at a preselected tempo for each circuit. Each circuit is connected to transmit an audio signal including a radio signal at the selected tempo, and a visual signal at the same tempo at a signal light in the orchestra. Each musician has a headphone to receive the audio signal for his group in the orchestra and each dancer has a miniaturized radio receiver and earphone to receive the radio signal for his group of dancers. A command system may also be provided to transmit verbal signals to a selected group or all of the groups of dancers and musicians.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
166 words
Metronome apparatus for signalling a plurality of tempi to artists performing at different tempi, comprising: a mechanically operated timer having a plurality of elements in a plurality of lines, the elements in each line being selectively regularly spaced to pass a given point at time spaced intervals, means continuously operable by each line of elements for operating a separate switch for each line of elements, each switch being in a separate electrical circuit including an audiofrequency generator, an amplifier and a relay, each amplifier being operably connected to at least one earphone, and each relay being operably connected in another separate circuit including an electrical source and at least one visual signal device, whereby each line of elements generates a regularly recurring audio signal at a chosen tempo which is conducted through an amplifier to a group of earphones worn by some of the artists and is conducted synchronously through a relay to one of the visual devices for transmitting different tempi to different orchestral artists.
Claim 2
Dependent Claim
166 words
Metronome apparatus for signalling a plurality of tempi to artists performing at different tempi, comprising: a mechanically operated timer having a plurality of elements in a plurality of lines, the elements in each line being selectively regularly spaced to pass a given point at time spaced intervals, means continuously operable by each line of elements for operating a separate switch for each line of elements, each switch being in a separate electrical circuit including an audiofrequency generator, an amplifier and a relay, each amplifier being operably connected to at least one earphone, and each relay being operably connected in another separate circuit including an electrical source and at least one visual signal device, whereby each line of elements generates a regularly recurring audio signal at a chosen tempo which is conducted through an amplifier to a group of earphones worn by some of the artists and is conducted synchronously through a relay to one of the visual devices for transmitting different tempi to different orchestral artists.
Claim 3
Dependent Claim
73 words
Apparatus defined in claim 1 wherein each amplifier is additionally electrically connected to a radio transmitter for sending a radio signal, the radio signals from the amplifiers being at different wavelengths, and a plurAlity of radio receivers tuned to said different wavelengths, each receiver having an earphone, the receivers and connected earphones being adapted to be worn concealed by different dance artists, whereby the different tempi are also transmitted to different ballet dancers.
Claim 4
Dependent Claim
36 words
Apparatus defined in claim 2 wherein each amplifier is additionally operably connected to a voice operated electrical signalling device, whereby voice and additional audio signals may be transmitted at will to the artists through the earphones.
