Unity of Perception

When we think of music in its linear form, we can isolate the different parameters in time and frequency. Even though used in a technical way, the term frequency can have many implications. For example, the way we usually think about an event which has a frequency of 0.1 Hz is not in the frequency domain, especially when we are thinking about music. The frequency domain in music is usually referred to as the way we perceive tones and their combinations, whose spectrum lies in the range of 20-20 KHz. This practice is strongly backed by the fact that we are not able to hear physical frequencies of less than 20 Hz[10, page 21].
