摘要： A sound element is generated by synthesizing, from a base sound, a frequency component of a sinusoidal wave one octave higher than the base sound. The base sound is a frequency component of one sinusoidal wave with an integer multiple of periods thereof matching a sample count represented by a power of 2. Sound elements having a frequency serving as a musical scale in a temperament are selected from the sound elements. The selected sound element is outputted in a predetermined pattern of time and a musical scale, so that a test tone is produced in a melody-like fashion.
