EQ adjusting to song key, reference

Archived from groups: rec.audio.pro (More info?)

I was wondering if anyone could recommend a chart that is a correlation
of EQ settings to song Keys. For Example; I have a pretty good 7 band
EQ in PTLE, and it would be helpful to know
what frequencies to notch for a quick starting place if a song was in
the key A or C or whatever.

Your question reveals one of the fundamental flaws in the
protools concept. <chuckle>

Crane Song has an equalizer called Ibis that has the knobs marked in
musical notes rather than frequency. There's a chart on the web page
that might be what you're asking for:

http://www.cranesong.com/IBIS%20FREQUENCY%20CHART.html

However, I don't see what you plan to do with an equalizer, knowing
what key a song is in. If you have a note that sticks out, you might
want to try to knock it down a bit, but you'll need an equalizer with
very good resolution.

I would never do what your discussing, but I think you should try it.
Depending on the method of the recording, the key of the song
absolutely will affect the sound you've recorded. For instance, if you
record a guitar with room mics, the room will resonate differently
withe certain frequencies and of course the key will determine what
frequencies you hit and hit most often.

I htink ther's a good chance that the mid frequency ou cut from teh
room will be influcned a bit by the key.

Still, if you ahve every note played translated to a frequency on a
chart infront, I still don't know how you'd know what to boost or cut.
Even if there was a book saying alwyas cut the fundamental or an octave
up, how would you know how much to cut? How do you know that your room
will resonate in a way that the person who wrote the book expects? How
do you know that their taste in results will match yours?

I htink it would be a great excercise to try ebcuase you never know
what you'll learn, but I think iwhat you will probably learn is that
you've got to EQ by ear, not by eye.

Well, I guess you could try, but it doesn't really work that way.

Unfortunately, 'apples' and 'Yes' are not exactly unrelated entities at all,
as witnessed by these lyrics from "Circus of Heaven" from Yes' (possibly
worst album) "Tormato":

"On the dreamy ground we walked upon
I turned to my son and said
'Was that something beautiful, amazing, wonderful, extraordinary beautiful?'
'Oh! it was OK!! But there were no clowns, no tigers, lions or bears,
candy-floss, toffee apples, no clowns.' "


Leave it to Jon Anderson, huh?

If you aren't Gabby Pahunui.

We still have an organ in town with A=335. It's no fun for accompanists
who not only have to retune but have to transpose.

OK

Assuming standard tuning - high E string, fifth fret = A440; G string,
second fret = 220; open A string = 110.

All in theory, of course. Much depends on the guitar, the strings, and
the player.

This begs the question regarding the crane Eq module.

Why does it give you the ability to adjust EQ curves to different keys
if there is no co relation (apples and oranges). Maybe it is a
marketing hoax? I think not.

Of course most eq tools will not allow you to be so specific in
frequencies to boost or cut. But especially on the low to mid end you
have an opportunity to zone into a sweet spot that is related to the
key. This is where the body of most tones reside. If I have a low end
that
I can notch between 40hz and 120, I would have a clue that a good place
to listen to would be around 55hz if it is the key of A and multiple up
the line.

I would defer to the notion that the ear is the arbitrator, but why not
apply
some science to the art? I am not going to get lost in defining every
track
with notch keyed EQs, but it is something to consider on specific
instruments.

That's pretty wild. Was it like one wall they could move in and out to
adjust to the key?

That's hardly wild in this day and age. I know of two recital halls in
this metro area that have adjustable acoustics. There are probably
more. One is Varner Hall and is at least a decade old, and the other
is in the new addition to Orchestra Hall.

I don't recall the exact details, but one moving wall would be the
simplest. I can only imagine the hydraulic controls for that one, A,
B, C#, Gb...

I believe the meters/feet etc refers to the length of one complete wave at
that frequency. Most likely valuable info for tuning a room or constructing
speaker cabinets and musical instruments.

"It doesn't. It allows you to adjust them to different NOTES.

You can think of a pure tone as either having a frequency or a pitch...

they are two different ways of thinking about the same thing in that
case. A complex note will have one pitch and several different
frequency components.
--scott "

Without a doubt. I guess the application would be for working on
individual
drums/cymbals, or as someone ointed out to pull down a note that is
always sticking out (probably a lot easier applying gain reduction in
daw).

I am thinking though; eq dialed into a key with tonic a perf 4th a
perf 5th maybe a maj 3rd or minor 3rd harmonic (major or minor keyed
song) could give an optimal resonance throughout the scale.

I don't think an aural exciter works on this principal ...something
about even harmonics, but maybe there is another rack device or
software plug in that might work on this concept. If not, then it is
something to be considered by an entrepreneur. Could be a great plug
in.

"Also, pianists (at least jazz pianists) voice
their chords in such a way that there is enough harmonic identity
without bombarding the listener with the tonic of the key (the latter
could also be known as power chords). If there's too much 'A' in an A
chord, it sounds lame, but if not even the bass player is playing an A,

it can sometimes get confusing as to what chord is actually going on.
This is responsible for many scary moments at jazz shows. Anyway, I
know this isn't really where you guys were taking this, but it may be
something to think about.
-steve "

I see what you are saying. Voicing considerations are often overlooked
by a lot of "musicians". Amazing the number of songs in which the bass
just parallels the roots of the chords. I had a music teacher (Juliard
educated) who said it didn't make much sense to him paying two players
to play the same line.

Little comments like that sick with you.
