Getting to know the frequency chart in your EQ might not be the easiest task. In the beginning a phrase like "would you take some of that 1k down a notch" probably won't mean much sound wise. Therefore it is a good idea to connect those frequency numbers with a descriptive word. The word Honky can describe 1khz a lot better and one can a lot easier connect that word to an actual sound. Look at the chart below to connect other words to the frequency spectrum!
The green words are positive words that you can add more of if you're looking for it. The red ones are areas to look for if you hear some problematic stuff in your audio.
