Abstract
The present disclosure relates to audio and music processing devices and methods. A system is provided that utilizes tonal and rhythmic visualization methods to accurately and empirically determine the level of similarity between two or more musical works.
Claims1
A system for comparing musical works, comprising:
- a processing device;
- and
- a display;
- wherein:
- said processing device executes computer readable code to create a first visual representation of a first musical structure for output on the display;
- wherein:
- said processing device executes computer readable code to create a second visual representation of a second musical structure for output on the display;
- wherein:
- said first visual representation is evaluated by a user to determine the level of similarity to said second visual representation;
- and
- wherein:
- said first visual representation and said second visual representation are generated according to a method comprising the steps of:
- (a) labeling the perimeter of a circle with twelve labels corresponding to twelve respective notes in an octave, such that moving clockwise or counter-clockwise between adjacent ones of said labels represents a musical half-step;
- (b) identifying an occurrence of a first one of the twelve notes within said musical structure;
- (c) identifying an occurrence of a second one of the twelve notes within said musical structure;
- (d) identifying a first label corresponding to the first note;
- (e) identifying a second label corresponding to the second note;
- (f) creating a first line connecting the first label and the second label, wherein:
- (1) said first line is a first color if the first note and the second note are separated by a half step;
- (2) said first line is a second color if the first note and the second note are separated by a whole step;
- (3) said first line is a third color if the first note and the second note are separated by a minor third;
- (4) said first line is a fourth color if the first note and the second note are separated by a major third;
- (5) said first line is a fifth color if the first note and the second note are separated by a perfect fourth;
- and
- (6) said first line is a sixth color if the first note and the second note are separated by a tri-tone.
