Patent ID: 6961288

Claim:
A sound-scale generation device comprising: a clock means counting a time and generating a sound generation instruction signal at a fixed time, a sound generator able to generate a sound of a 12-sounds scale, a sound generating controller linking a sound of each sound-scale of the 12-sounds scale and a time corresponding to the fixed time and controlling the sound generator so as to generate a basic sound defined as one sound of the 12-sounds scale, and generate a first scale-forming-sound corresponding to the time at which the sound generating controller receives the sound generation instruction signal, and a harmonic-sound forming 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 first scale-forming-sound when the sound generating controller makes the sound generator generate a second scale-forming-sound of a dissonant interval and/or imperfect consonant interval with respect to the basic sound.
