Abstract
Abstract An arrangement is provided for generating and recording signals of different frequency corresponding to the different beats in the meter of musical material simultaneously with the recording of the musical material. During playback the signals are detected according to their frequency and are utilized to illuminate individual ones of a plurality of lamps in synchronism with the beats of the musical material as the musical material is played back. The illuminated lamps are used by one or more performers to render a live performance in perfect synchronism with playback of the recorded musical material.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
185 words
A method of rendering a second musical performance in synchronism with the playback of a recorded first musical performance comprising the steps of: recording the first musical performance as said first performance occurs; generating a sequence of signals simultaneously with the occurrence of each measure of said first performance, each sequence of signals comprising an ordered set of signals uniquely associated with the order and timing of the beats in each measure as performed; recording said sequence of signals simultaneously with said recording of said first performance; playing back said recorded first performance and said sequence of signals simultaneously; providing an ordered set of indicators to be sensed by the performer of said second musical performance, each of said indicators being actuated by said played back ordered set of signals, whereby each of said indicators is associated with a particular beat of each measure of said first performance; and rendering said second performance having beats therein in synchronism with said actuated indicators, whereby the beats of said second performance are in synchronism with the order and timing of the corresponding beats of said first performance.
Claim 2
Independent Claim
185 words
A method of rendering a second musical performance in synchronism with the playback of a recorded first musical performance comprising the steps of: recording the first musical performance as said first performance occurs; generating a sequence of signals simultaneously with the occurrence of each measure of said first performance, each sequence of signals comprising an ordered set of signals uniquely associated with the order and timing of the beats in each measure as performed; recording said sequence of signals simultaneously with said recording of said first performance; playing back said recorded first performance and said sequence of signals simultaneously; providing an ordered set of indicators to be sensed by the performer of said second musical performance, each of said indicators being actuated by said played back ordered set of signals, whereby each of said indicators is associated with a particular beat of each measure of said first performance; and rendering said second performance having beats therein in synchronism with said actuated indicators, whereby the beats of said second performance are in synchronism with the order and timing of the corresponding beats of said first performance.
Claim 3
Dependent Claim
48 words
The method of claim 1 wherein the step of generating a sequence of signals comprises listening to said first performance as it occurs and manually actuating a plurality of signal generators in predetermined order in synchronism with the occurrence the beats in each measure of said first performance.
Claim 4
Dependent Claim
21 words
The method of claim 1 further comprising the step of recording said played back first performance and said rendered second performance.
Claim 5
Dependent Claim
