Abstract
Abstract Method and apparatus for accentuating beats in a musical arrangement. A continuous loop of film is prepared containing sequential sets of different images. A predetermined number of the images is projected for no more than one-third of a second ensuring that there is a discrete image change within one-sixth of a second of the time of occurrence of a beat.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
94 words
A method of accentuating beats in a musical arrangement having a tempo, said method comprising the steps of preparing a motion picture film having frames to contain sequential sets of different images, each of said sets comprising a plurality of substantially identical frames, each of said sets being different from adjacent sets, and projecting a predetermined number of sets of sequential images for a time duration of no greater than onethird of a second whereby a discrete image change occurs within approximately one-sixth of a second of the time of occurrence of a beat.
Claim 2
Independent Claim
94 words
A method of accentuating beats in a musical arrangement having a tempo, said method comprising the steps of preparing a motion picture film having frames to contain sequential sets of different images, each of said sets comprising a plurality of substantially identical frames, each of said sets being different from adjacent sets, and projecting a predetermined number of sets of sequential images for a time duration of no greater than onethird of a second whereby a discrete image change occurs within approximately one-sixth of a second of the time of occurrence of a beat.
Claim 3
Dependent Claim
27 words
A method as set forth in claim 1, wherein a majority of said sets of different images are projected for no greater than one-third of a second.
Claim 4
Dependent Claim
26 words
A method as set forth in claim 1, including the additional step of forming a continuous loop of film containing said sequential sets of different images.
Claim 5
Dependent Claim
28 words
A method as set forth in claim 3, including the additional step of projecting successive ones of said sequential sets of different images for progressively increasing time durations.
Claim 6
Dependent Claim
34 words
A method as set forth in claim 3, including the additional step of preparing said continuous loop of film to contain multiple images on frames of said motion picture film to be simultaneously projected.
Claim 7
Dependent Claim
91 words
Apparatus for accentuating beats in a musical arrangement having a tempo, said apparatus comprising a continuous loop of film having a plurality of frames, sequential sets of different images being contained on said frames, each of said sets comprising a plurality of substantially identical frames, each of said sets being different from adjacent sets, a predetermined number of said sets of different images being placed on a predetermined number of frames such that said predetermined number of sets of different images are projected for no greater than one-third of a second.
Claim 8
Dependent Claim
91 words
Apparatus for accentuating beats in a musical arrangement having a tempo, said apparatus comprising a continuous loop of film having a plurality of frames, sequential sets of different images being contained on said frames, each of said sets comprising a plurality of substantially identical frames, each of said sets being different from adjacent sets, a predetermined number of said sets of different images being placed on a predetermined number of frames such that said predetermined number of sets of different images are projected for no greater than one-third of a second.
Claim 9
Dependent Claim
25 words
Apparatus as set forth in claim 6, wherein 24 frames a second are projected and said predetermined number of frames is no greater than eight.
Claim 10
Dependent Claim
13 words
Apparatus as set forth in claim 6, wherein said frames include multiple images.
Claim 11
Dependent Claim
33 words
Apparatus as set forth in claim 6, wherein said predetermined number of said sets of different images is more than a majority of all the different images on said continuous loop of film.
