Claims

[Claims for Utility Model Registration] 1. Accompaniment pattern storage means for storing accompaniment patterns, a performance operator for inputting at least arbitrary chord information, chord information input by the performance operator, and the accompaniment pattern storage means an automatic accompaniment device that performs automatic accompaniment based on an accompaniment pattern stored in the instrument, comprising: a first instruction means for instructing storage of chord information input by the performance operator; and an instruction of the first instruction means. a second instruction means for instructing the chord information storage means to stop storing the chord information; a third instruction means for instructing the chord information storage means to stop storing the chord information; instruction means; and according to instructions from the second instruction means, instead of the chord information input by the performance operator, chord information stored in the chord information storage means is repeatedly read in the order in which it is stored; Accompaniment information is created based on the chord information stored in the accompaniment pattern storage means and the accompaniment pattern stored in the accompaniment pattern storage means, and when an instruction is given by the third instruction means during the creation, the performance operator is again activated. an automatic accompaniment device comprising: accompaniment information creation means for creating accompaniment information based on chord information input by the accompaniment pattern storage means and accompaniment patterns stored in the accompaniment pattern storage means. 2. The chord information storage means, when instructed by the first instruction means, starts the performance when the automatic accompaniment pattern read from the accompaniment pattern storage means reaches the performance timing of the beginning of the beat of the next measure. When storage of the chord information inputted by the operator is started and an instruction is given by the second instruction means, the accompaniment pattern read from the accompaniment pattern storage means is set at the performance timing of the end beat of the next measure. 2. The automatic accompaniment apparatus according to claim 1, wherein storage of the chord information input by said performance operator is terminated at the point in time when said performance operator is inputted. 3. A performance operator for inputting at least arbitrary chord information and pitch information, an accompaniment pattern storage means for storing an accompaniment pattern, and chord information input by the performance operator and stored in the accompaniment pattern storage means. An electronic musical instrument comprising: an accompaniment signal creation means for creating an accompaniment signal based on an accompaniment pattern; and a pitch signal creation means for creating a pitch signal based on pitch information inputted by the performance operator. a first instruction means for instructing storage of chord information input by a performance operator; and a chord information storage means for starting storage of chord information input by the performance operator in response to an instruction from the first instruction means. a second instruction means for instructing the chord information storage means to stop storing the chord information; a third instruction means; Instead of the chord information stored in the accompaniment pattern storage means, chord information stored in the chord information storage means is sequentially and repeatedly read out in the order in which they are stored, and based on the read chord information and the accompaniment pattern stored in the accompaniment pattern storage means. , when accompaniment information is created, and during the creation, an instruction is given by the third instruction means, the chord information inputted by the performance operator and the accompaniment pattern stored in the accompaniment pattern storage means are again combined. An electronic musical instrument comprising: accompaniment information creation means for creating accompaniment information based on the accompaniment information. 4. The chord information storage means, when instructed by the first instruction means, starts the performance when the automatic accompaniment pattern read from the accompaniment pattern storage means reaches the performance timing of the beginning of the beat of the next measure. When storage of the chord information inputted by the operator is started and an instruction is given by the second instruction means, the accompaniment pattern read from the accompaniment pattern storage means is set at the performance timing of the end beat of the next measure. 4. The automatic accompaniment apparatus according to claim 3, wherein storage of the chord information inputted by the performance operator is terminated at the point in time when the chord information is inputted by the performance operator. 5. The electronic musical instrument according to claim 3, wherein the performance operator comprises a keyboard, and the keyboard is divided into two areas: a pitch information input area and a chord information input area. 6. When the accompaniment information creation means is creating accompaniment information using the chord information stored in the chord information storage means according to the instruction from the second instruction means, all keys of the keyboard are set to pitch. 6. The electronic musical instrument according to claim 5, further comprising setting means for setting so that only information can be input.
