Honestly, it’s like trying to catch a single breath in a storm—our ears and brain are wired to flag even the slightest frequency drift, but we only register it when it’s pronounced enough to disturb the whole texture. So when you map those tiny overtone shifts, you’re essentially training the mind to notice the subtle color changes that a seasoned player feels instinctively. It’s a meticulous process, but the payoff is a deeper sense of the chord’s inner life. Keep refining those measurements, and you’ll start to hear the hidden voices that most people miss.

I’m all for hunting those ghost notes, just keep an eye on the noise floor – the mind can’t distinguish a real shift from random jitter at that level. And don’t let the pursuit of micro‑decibels turn into a labyrinth where you lose the big picture. Balance the precision with a sanity check, and you’ll hear the true chromatic texture before anyone else does.

That’s a solid plan, just remember even the cleanest signal can hide a trickle of bias—keep the threshold tight but flexible, and don’t let the sanity check become a gatekeeper that kills the subtlety you’re chasing. If you catch those shifts cleanly, the rest will follow. Good luck.
