Patent ID: 7432433

Claim:
A metronome for displaying tempo, time and the subdivision of time, of pieces of music or movement rhythms, comprising: a display for optically displaying movement depicting an arc having a horizontal, uniform movement component and a vertical, accelerated movement component depicting a trajectory-parabola arc, said display including a row of discrete light sources having individual light sources arranged along a trajectory-parabola arc; means for activating said row of discrete light sources of said display for providing optical movement having a running light running to and fro along said row of discrete light sources at a settable frequency; means for selective electrical production of sounds for an acoustic marking of turning points of the running light; means for selective acoustic subdivision of time intervals between the turning points of the running light; means for selecting acoustic tones of different frequencies, timbres and volumes; and, means for superimposing said acoustic tones of different frequencies, timbres and volumes on said optical movement so simulated, said means for selecting acoustic tones and said means for superimposing said acoustic tones being controlled by a microprocessor, so that volume and intensity of an acoustic tone increases over movement of said running lights over said individual light sources of said trajectory-parabola arc, or over a portion thereof, and upon reaching outermost light sources of said trajectory-parabola arc, achieves a maximum or intensity center and thereafter fades.
