2d user interface for a musical instrument for playing combined sequences of chords and tunes, and computer-readable storage medium

A method for producing combined chord and tune sequences using a user interface for a musical instrument for playing combined chord and tune sequences, comprising a key matrix (1) with a plurality of zones (111, 121, . . . ;

• 112, 122, . . . ;
• 11n, 12n, . . . ) which are arranged in columns and rows, wherein each row of activatable zones (111, 121, 112, 122, . . . ;
• 11n, 12n, . . . ) forms a region (101, 102, . . . ), wherein each region (101, 102, . . . ) is associated with a basic chord, which is preferably a chord of a scale, preferably a diatonic scale, the chord being specific to the scale, wherein each zone (111, 121, . . . ;
• 112, 122, . . . ;
• 11n, 12n, . . . ) is associated with a musical tone, which is preferably a musical tone of a scale, wherein the user interface is designed to produce, when a zone (111, 121, . . . ;
• 112, 122, . . . ;
• 11n, 12n, . . . ) in a region (101, 102) is activated, a musical tone-producing command corresponding to the activated zone (111, 121, . . . ;
• 112, 122, . . . ;
• 11n, 12n, . . . ) and region (101, 102, . . . ), wherein the musical tone-producing command comprises at least one basic chord note command with a pitch which is contained in the basic chord associated with the activated region (101, 102, . . . ), and comprises a tune note command, the pitch of which corresponds to the musical tone of the activated zone (111, 121, . . . ;
• 112, 122, . . . ;
• 11n, 12n, . . . ), preferably by using a musical instrument, comprising the following steps:
• provision of the user interface;
• reception of a user input when a zone (111, 121, . . . ;
• 112, 122, . . . ;
• 11n, 12n, . . . ) of the key matrix (1) is activated;
• producing a musical tone-producing command corresponding to the activated zone (111, 121, . . . ;
• 112, 122, . . . ;
• 11n, 12n, . . . ).
