Abstract

Abstract An electronic musical instrument generates musical tones corresponding to a melody tone and a chord tone which are designated by a performer. In order to apply a specific musical effect or generate an ornament, a front percussive tone, or forefall, is automatically added to the melody tone, wherein this front percussive tone has the predetermined pitch difference with respect to the melody tone. This front percussive tone is additionally generated prior to the melody tone in the predetermined short period. Instead of this front percussive tone, it is possible to generate an additional tone which has the same tone name as any one of constituent tones within the chord tone but its tone pitch is different from that of the melody tone. When generating plural melody tones and plural additional tones, these tones are sequentially generated by a predetermined time difference in a pitch descending or ascending order.

Independent Claim 167 words
An electronic musical instrument comprising: (a) melody designating means for designating a melody tone to be generated; (b) chord designating means for designating a chord tone to be generated; (c) musical tone signal generating means for generating a musical tone signal; (d) means for determining whether or not additional tones are to be generated, wherein a first additional tone has the same tone name as any one of constituent tones within said chord tone and a tone pitch between that of said first melody tone and a second additional tone which has a pitch difference of one or more octaves with respect to said melody tone; and (e) control means for generating a musical tone generation control signal, by which said musical tone signal generating means is controlled such that musical tone signals corresponding to said first additional tone, said second additional tone and said melody tone are sequentially generated by a predetermined time difference in a predetermined pitch order wherein said melody tone is generated last.
Claim 2
Dependent Claim 167 words
An electronic musical instrument comprising: (a) melody designating means for designating a melody tone to be generated; (b) chord designating means for designating a chord tone to be generated; (c) musical tone signal generating means for generating a musical tone signal; (d) means for determining whether or not additional tones are to be generated, wherein a first additional tone has the same tone name as any one of constituent tones within said chord tone and a tone pitch between that of said first melody tone and a second additional tone which has a pitch difference of one or more octaves with respect to said melody tone; and (e) control means for generating a musical tone generation control signal, by which said musical tone signal generating means is controlled such that musical tone signals corresponding to said first additional tone, said second additional tone and said melody tone are sequentially generated by a predetermined time difference in a predetermined pitch order wherein said melody tone is generated last.
Claim 3
Dependent Claim 43 words
An electronic musical instrument according to claim 1 further comprising prohibiting means for controlling said means to prohibit generation of a first additional tone having a tone pitch which is relatively close to that of said melody tone or said second additional tone.
Claim 4
Dependent Claim 20 words
An electronic musical instrument as set out in claim 1, wherein aid predetermined pitch order is a pitch ascending order.
Claim 5
Dependent Claim 20 words
An electronic musical instrument as set out in claim 1, wherein said predetermined pitch order is a pitch descending order.
Claim 6
Dependent Claim 266 words
An electronic musical instrument comprising: (a) melody designating means for designating a first melody tone to be generated; (b) chord designating means for designating a chord tone to be generated; (c) musical tone signal generating means for generating a musical tone signal; (d) first selecting means for selecting plural additional tones to be additionally generated, wherein each of said additional tones has the same tone name as any one of constituent tones within said chord tone and a tone pitch between that of said first melody tone and an added melody tone which has a pitch different of one or more octaves with respect to said first melody tone; (e) excluding means for excluding certain additional tones from said plural additional tones, wherein each of said certain additional tones to be excluded has a tone pitch which is relatively close to that of said first melody tone or said added melody tone; (f) second selecting means for selecting a certain number of additional tones from said additional tones which are selected by said first selecting means but not excluded by said excluding means, wherein said certain number of additional tones are decided by a priority order corresponding to said chord tone; and (g) control means for generating a musical tone generation control signal, by which said musical tone signal generating means is controlled such that musical tone signals corresponding to said first melody tone, said added melody tone and said certain number of additional tones are sequentially generated by a predetermined time difference in a pitch descending order wherein said first melody tone is generated last.
Claim 7
Dependent Claim 266 words
An electronic musical instrument comprising: (a) melody designating means for designating a first melody tone to be generated; (b) chord designating means for designating a chord tone to be generated; (c) musical tone signal generating means for generating a musical tone signal; (d) first selecting means for selecting plural additional tones to be additionally generated, wherein each of said additional tones has the same tone name as any one of constituent tones within said chord tone and a tone pitch between that of said first melody tone and an added melody tone which has a pitch different of one or more octaves with respect to said first melody tone; (e) excluding means for excluding certain additional tones from said plural additional tones, wherein each of said certain additional tones to be excluded has a tone pitch which is relatively close to that of said first melody tone or said added melody tone; (f) second selecting means for selecting a certain number of additional tones from said additional tones which are selected by said first selecting means but not excluded by said excluding means, wherein said certain number of additional tones are decided by a priority order corresponding to said chord tone; and (g) control means for generating a musical tone generation control signal, by which said musical tone signal generating means is controlled such that musical tone signals corresponding to said first melody tone, said added melody tone and said certain number of additional tones are sequentially generated by a predetermined time difference in a pitch descending order wherein said first melody tone is generated last.
Claim 8
Dependent Claim 293 words
An electronic musical instrument, comprising: (a) melody keyboard means which is performed by a performer so that a desirable tone pitch of a melody tone to be sounded is designated; (b) accompaniment keyboard means which is performed by a performer so that a desirable chord tone to be sounded is designated; (c) operator control means capable of designating at least a tone color and a tone volume of a musical tone to be sounded; (d) memory means for storing data concerning additional tones to be additionally sounded with said melody tone, said memory means comprising: (i) a first table for pre-storing data indicative of front percussive tones as said additional tones, desirable one of said front percussive tones corresponding to said melody tone to be presently designated being automatically and additionally sounded prior to said melody tone; and (ii) a second table for pre-storing other data indicative of arpeggio tones as said additional tones, said arpeggio tones corresponding to each chord tone so that desirable arpeggio tones are automatically selected in accordance with a chord type of said chord tone designated by said accompaniment keyboard means; said desirable arpeggio tones being sounded with a predetermined time difference in a sequence ending with said melody tone, (e) musical tone signal generating means for generating a musical tone signal; and (f) control means for controlling said musical tone signal generating means, said control means automatically and arbitrarily selecting one or more additional tones from said memory means, whereby, under control of said control means and said operator control means, said musical tone signal generating means generates musical tone signals based on said chord tone, said melody tone and said additional tone, so that desirable musical tones are to be sounded based on said musical tones.
