How do you interpret frequency domain?

The Frequency Domain refers to the analytic space in which mathematical functions or signals are conveyed in terms of frequency, rather than time. For example, where a time-domain graph may display changes over time, a frequency-domain graph displays how much of the signal is present among each given frequency band.

What is meant by the frequency domain?

In engineering and statistics, frequency domain is a term used to describe the analysis of mathematical functions or signals with respect to frequency, rather than time. The most common purpose for analysis of signals in the frequency domain is the analysis of signal properties.

Why do we use frequency domain instead of time domain?

In this case, the frequency-domain analysis gives a better understanding than time domain analysis because music is tacitly based on the breaking down of intricate sounds into their separate component frequencies. An oscilloscope is an invaluable tool for detecting signals.
