Abstract

A sound-scale generation device and time-announcing clock eliminating the unpleasantness when a sound of a dissonant interval or imperfect consonant interval is generated, provided with a clock circuit generating a sound generation instruction signal at a fixed time, a frequency divider serving as a sound generator able to generate at least a 12-sounds scale, an amplifier, a speaker, a sequential switching circuit linking the 12-sounds of the 12-sounds scale and times corresponding to the fixed time and controlling the sound generator so as to generate a basic sound of one sound of the 12-sounds scale, then generate scale-forming-sounds corresponding to a time every time receiving a sound generation instruction signal, and a harmonic-sound adder controlling the sound generator so as to generate a sound by superposing at least one of the harmonic-sound forming sounds able to form a harmonic-sound including the scale-forming-sound when the sequential switching circuit makes the sound generator generate at least a scale-forming-sound of a dissonant interval and/or imperfect consonant interval with respect to the basic sound.
