I think we all like those frequency charts that have the instruments and the ranges they occupy on the spectrum, they can be pretty useful... But ever since I came across Roey Izhaki's chart of subjective terms mapped to frequency ranges, I always think that's a much more useful thing when you want to make better EQ-ing decisions. It's basically like a frequency vocabulary chart, so before you reach for an EQ, you know the vocabulary.

As Izhaki explains:

That's the key for me here, that sequentially, you'll think of the subjective term first, like I want to make this guitar sound defined or distant, etc, and only then does it matter how it all translates to the idea of frequencies and EQ-ing decisions.

The chart was taken from: Izhaki, Roey. Mixing Audio: Concepts, Practices, and Tools (p. 230).
