Abstract
An arrangement for forming a musical chord signal in which there are provided a frequency divider for root, a frequency divider for minor third, a frequency divider for major third and a frequency divider for fifth or a frequency divider for seventh. These are connected in common and to an input terminal of a tone source signal. The frequency divider for minor third and the frequency divider for major third have a selection circuit for selectively taking out an output signal according to a major chord or a minor chord of music. The input terminal is connected through plural key-switches to the plural tone source signal oscillators. The output terminals of the frequency divider for root, the selective circuit and the frequency divider for fifth or the frequency divider for seventh are connected together through respective gate circuits which are opened and closed by an output pulse signal of a rhythm pulse generator.
