OK in all my years producing, I have never EQed frequencies to accentuate the root key for tuning. How is this done? I dont understand this at all. All I know is that each root key has a dominant frequency but how the heck do you apply this? How do you EQ with this in mind? Total newb when it comes to this process. Thank you guys. |

The frequency analyzer is your friend... Also somewhere in this forum is a link to the fundamental frequencies of notes. That should assist you in finding out what the root frequency is and from there you can use simple mathematics to discover where your frequencies might clash at. But it's definitely a combination of using a frequency analyzer and a good pair of ears to figure out who's drowning who out and where you can apply a little frequency cut to help things out....

SO u use the key frequencies to determine where stuff might clash? Like I dont get what this gives you. Are you supposed to boost the frequency where the root note is? |

No. but the fundamental frequency will tell you where the meat of the sound should start at. From there you can see where in conjunction with the frequency analyzer where the odd harmonics are that might be clashing one sound with the other.. So for instance your acidline has a fundamental frequency of say 277.18 hz and your melody which is in the same key has a fundamental frequency of 1108.73 hz... Now if you do the math, the melody is roughly the multiple of 4 from the acidline, which means you could get away with cutting the acidline at either 1108.73 or (1200hz roughly) and you could boost the acidline at around 830 hz while cutting the melody at 830 and doing a slight boost at either around 1200 or 2400hz...
And who says basic math has nothing to do with music production???
Musical tones are made from harmonics which are mathematical multiples of a base frequency. Each sound is rarely a pure tone, which is a tone made strictly from a base frequency, but a collection of tones made from the harmonics combined with some odd harmonics in there to give the sound a little more character.... (at least that's what I think... )
So see if any of that helps you and I hope all goes well.

I use this when writing tracks where the kick and bass occur at the same time - I'll throw an EQ on the kick and notch out the fundamental plus a few integer multiples of the fundamental of the kick to give the bass some room to poke through.
This logic can apply to sound FX, especially if they are clashing with a melody.
If you've got a sound effect that's clashing with a melody try notching out the most common (or common) notes of the melody in the sound effect. If you wanted to get really precise you could automate an EQ to jump around on the sound effect with the melody, creating a 'hole' wherever a note was hitting.
But that would be insane.
...
Yes, I plan to try it sometime.  |

analyser on each track, freeze and compare... what you have in mind.. try here, try there, keep in mind mubalis tips on the fundamentals and harmonics, and leave it when you feel it's ok

only in space you'd be able to capture a sound that is a pure tone, but for that space couldn't be unsoundable(?)
just guessing

OK Im starting to understand now. Lemme say how I understand it to make sure you guys agree. So for Kick and basline, basically you would use a NOTCH to cut out part of the kick at the corresponding root key frequency (and its multiples), so the bassline has room to slip in more at that frequency. If 2 synths are competing like a Lead and Acidline, you can get away with cutting the multiples because the fundamentals are different.
Makes sense. But what happens when you have bassline key changes? Are you seriously automating the notch to move? Sounds painful as hell. But making ur songs sound pro never is easy 
Cheers guys! |

Personally, I tend to notch both the kick and the bass in different places... For instance, I'll notch my kick slightly around 410 hz or so and I'll notch my bass around 200ish or so... I'm lazy and don't automate the notch for key changes, but I haven't run into any issues there for me... But this is also because I am lazy to that extent. You honestly could do automate the notch to move or set up a secondary eq plugin that has the notch for the bassline change and have it bypassed untill it's needed. Automate the eqs to turn off and on when neccesarry.
