Where every common instrument's notes actually sit in hertz, why almost nothing has a fundamental above 4 kHz, and the fixed resonances that stay put when the note moves — the difference that turns EQ from guesswork into arithmetic.
Most EQ advice is a frequency and an adjective. Boost 3 kHz for presence. Cut 400 for mud. Add air at 12k. None of it is wrong exactly, and none of it is usable, because the same frequency does completely different things depending on what is there — and what is there is decided by two separate mechanisms that behave in opposite ways.
