Electronic musical instrument having automatic ornamental effect

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.

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.
