“A man who mistakes secrets for knowledge is like a man who, seeking light, hugs a candle so closely that he smothers it and burns his hand.”

You might wanna think about that someone wanting to learn how to F chord is gonna be a beginner and have absolutely no idea about note pitches, Hz and not know the notes on the fretboard - so talking about that will be really confusing to them.
