Abstract
Abstract Rhythm patterns are created by producing primitive data not having any fixed meaning and by associating the primitive data with desired creating parameters among a plurality of creating parameters for specifying meanings of the primitive data. The rhythm patterns may be created by storing a rule data base for associating a plurality of parameters specifying the features of rhythm and a plurality of rhythm patterns beforehand in a memory, entering the plurality of parameters, making reference to the rule data base on the basis of the plurality of input parameters, and creating the desired rhythm patterns by an inference system. It is also possible to create the rhythm patterns by extracting predetermined choices of at least some of a plurality of parameters specifying the features of desired rhythm for each part of a piece of music, creating rhythm patterns respectively for the parts of the piece of music from the choices extracted from the parameters for the parts of the piece of music and integrating the rhythm patterns for the entire piece of music.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A rhythm creating system comprising: an input means for entering a plurality of parameters specifying the genre and meter of the rhythm to be created; a memory for storing a rule data base for associating the parameters with rhythm patterns including a LEVEL rule specifying complexity of the desired pattern, and a LENGTH rule specifying a number of bars of a rhythm pattern to be created; and a rhythm pattern creating means for creating desired rhythm patterns by an inference system with reference to the rule data base on the basis of the plurality of parameters entered by the input means.
Claim 2
Dependent Claim
101 words
A rhythm creating system comprising: an input means for entering a plurality of parameters specifying the genre and meter of the rhythm to be created; a memory for storing a rule data base for associating the parameters with rhythm patterns including a LEVEL rule specifying complexity of the desired pattern, and a LENGTH rule specifying a number of bars of a rhythm pattern to be created; and a rhythm pattern creating means for creating desired rhythm patterns by an inference system with reference to the rule data base on the basis of the plurality of parameters entered by the input means.
Claim 3
Dependent Claim
70 words
A rhythm creating system according to claim 1 wherein said memory stores rules comprising an IDEA rule specifying the instrumentation of musical instruments to be used in the rhythm pattern, a METER rule specifying a number of beats of one bar of the rhythm pattern, a Ptn rule specifying the type of use to be made for the desired rhythm pattern, and a genre of rhythm patterns to be created.
Claim 4
Dependent Claim
32 words
A rhythm creating system according to claim 1, wherein said rhythm pattern creating means is provided with said inference system which creates different rhythm patterns from the plurality of the same parameters.
Claim 5
Dependent Claim
30 words
A rhythm creating system according to claim 1, wherein said rhythm pattern creating means is provided with a means for creating new rhythm patterns by operating the created rhythm patterns.
Claim 6
Dependent Claim
22 words
A rhythm creating system according to claim 1, wherein said rhythm pattern creating means assigns musical instruments to the created rhythm patterns.
Claim 7
Dependent Claim
23 words
A rhythm creating system according to claim 1, wherein said rhythm pattern creating means assigns musical time lengths to the created rhythm patterns.
Claim 8
Independent Claim
117 words
A method of generating a rhythm pattern for a piece of music, the method comprising the steps of: (a) inputting a plurality of parameters specifying the genre and meter of the rhythm to be created; (b) extracting a plurality of rhythm pattern creation instructions by applying inference rules to the parameters, said inference rules representative of the type of rhythm pattern to be created including a LEVEL rule specifying complexity of the desired pattern and a LENGTH rule specifying a number of bars of a rhythm pattern to be created; (c) creating a rhythm pattern in accordance with the rhythm pattern creation instructions extracted in step (b); and (d) storing the rhythm pattern created in step (c).
Claim 9
Independent Claim
117 words
A method of generating a rhythm pattern for a piece of music, the method comprising the steps of: (a) inputting a plurality of parameters specifying the genre and meter of the rhythm to be created; (b) extracting a plurality of rhythm pattern creation instructions by applying inference rules to the parameters, said inference rules representative of the type of rhythm pattern to be created including a LEVEL rule specifying complexity of the desired pattern and a LENGTH rule specifying a number of bars of a rhythm pattern to be created; (c) creating a rhythm pattern in accordance with the rhythm pattern creation instructions extracted in step (b); and (d) storing the rhythm pattern created in step (c).
Claim 10
Dependent Claim
55 words
The method of generating a rhythm pattern as recited in claim 7, wherein said step (b) further comprises the step of inputting rules of: identification of which types of percussion instruments will be emulated in the created rhythm pattern; and a meter specifying the number of beats of one bar of the created rhythm pattern.
Claim 11
Dependent Claim
85 words
The method of generating a rhythm pattern as recited in claim 7, wherein said step (b) further comprises the step of inputting: a name of each pattern of a plurality of rhythm patterns to be created by the rhythm pattern generating method to be reproduced respectively during playback of a plurality of parts of the piece of music; and an identification of a type, such as an introductory or fill type, of rhythm pattern corresponding to each named rhythm pattern input in said step (b).
Claim 12
Dependent Claim
44 words
The method of generating a rhythm pattern as recited in claim 7, wherein the type of music input in said step (b) is one of a funky rhythm (FUNK), rock `n` roll rhythm (ROCK), jazz rhythm (JAZZ), metal rhythm (METAL), and reggae rhythm (REGGAE).
