Electronic musical instrument with a melody and rhythm generator

An electronic musical instrument comprising:

• (a) melody designating means for designating a melody tone;
• (b) chord designating means for designating a chord;
• (c) rhythm designating means for designating a rhythm which includes a predetermined tone-generation pattern of an additional tone to be added to said melody tone;
• (d) detecting means for detecting whether or not a pitch of said melody tone is higher than a predetermined pitch;
• (e) varying means for varying a forming pattern of said additional tone based on a detection result of said detecting means;
• and
• (f) adding means for adding the additional tone to said melody tone in accordance with the melody tone, the chord, and varied pattern.

An electronic musical instrument comprising:

• (a) melody designating means for designating a pitch of a melody tone;
• (b) chord designating means for designating a chord;
• (c) musical tone signal generating means for generating a musical tone signal corresponding to said melody tone and said chord;
• (d) rhythm selecting means for selecting a rhythm kind;
• (e) rhythm tone control means for controlling a rhythm tone signal to be generated by a predetermined timing in response to the rhythm kind and its rhythm progression selected by said rhythm selecting means;
• (f) rhythm tone generating means for generating a rhythm tone corresponding to said rhythm tone signal;
• (g) additional tone control means for controlling an additional tone to be added to said melody tone in response to the pitch of said melody tone, the chord and the rhythm progression, said musical tone signal also corresponding to said additional tone;
• (h) pattern control means for controlling a forming pattern of said additional tone in response to a selected rhythm kind;
