Sound spectrum

Music is a sound. And sound is a sine wave. The frequency of this wave determines whether it is perceived as low or high pitched. The higher the frequency the more high pitched is the heard sound. Alternatively, the lower this frequency is the lower the sound is. The sound spectrum which is perceptible by the human ear ranges from the limits of infrasound (2O Hertz) to ultrasound (20,000 Hertz).
