I'm actually getting really into this harmonic topic and the more I read around, the more I understand many things going on in sound. Pariticolary useful when apply this knowledge of harmonics to eq and mixing.

What do you guys know about it and how(if) you apply the eq relating harmonic and fundamental correlation?
Has someone in here a secret that he want to share on how to play around with harmonic mix and eq?
I've been reading around that you can gain huge benefits by controlling the harmonic balance and clashes in a mix. But I can't hide that I've never been aware about it and I've been always work only using my ears, really not caring about this science... But now... I have cricket in my head!
