Claims

[Scope of utility model registration request]

An electronic musical instrument, a tempo control operator provided on the electronic musical instrument, an automatic accompaniment means provided on the electronic musical instrument, a clock source that generates a clock signal, and a clock source provided on the electronic musical instrument that separates the clock signal. a first counter that rotates to generate a tempo clock signal, an automatic performance machine that records and reproduces performance information of the electronic musical instrument, a tempo correction operator provided on the automatic performance machine, and a tempo correction operator provided on the automatic performance machine; and a second counter that divides the frequency of the tempo clock signal to generate a tempo clock signal, and the performance information recorded by the automatic performance machine includes tempo data corresponding to the operation amount of the tempo control operator. The first and second counters divide the clock signal at a frequency dividing ratio according to the operation amount of the tempo control operator when recording the performance information, and divide the clock signal at a division ratio corresponding to the operation amount of the tempo control operator when recording the performance information, and when reproducing the performance information. The frequency of the clock signal is divided according to the tempo data and the operation amount of the tempo correction operator, and the automatic accompaniment means divides the frequency of the clock signal based on the amount of the tempo clock signal from the first counter. , and the automatic performance machine reproduces the performance information based on a tempo clock signal from the second counter.
