Would it be true that if you take the fifth note in a scale (such as a G below in C major scale) and then take the letter to the left of it and make it sharp it will be the correct in the key? Sorry if I didn't explain it well.


For example:


C D E F G A B C


Fifth is G. Behind it is F. F ----> F#


G A B C D E F# G

does this work? Would it be true?

F is F# in the key of G, so you're right there. I've never used that way of figuring out key signatures, there are much easier ways. I don't think that will always work anyways, look at C for example.

if you go up in fifths you will make the circle of fifths coming back to C eventually

if you start in the key of C and go to the fifth which is g you are now in the key of g and add one sharp. if you go a fifth from g you are in D and have 2 sharps, and so on. if you want to figure out flats from C just go to the fourth which is F, then Eb, then Ab, etc. I hope thats not too confusing.

That should make sense. In C, the 5th is G. The Mixolydian mode with C as the parent scale is G Mixolydian. If you raise the b7 of G Mixolydian, you get G major.

^ sprry i am a little confused

so my question is what does this have to do wiht raising the b7?

not to sound rude or anyhting

The note to the left of G is F. F is the b7 in the G Mixolydian scale. Raising F to F# yields the G Major scale (or C Lydian or any number of scales depending on what you consider the root, but consider it G).

Snap, that's useful. Thanks BGC.

Thank you, but while what I said is correct, I'm not sure it is actually useful.


The relationship is definately true, but I can't see how other aspects of theory don't cover it.

Perhaps it's good to look for these little patterns. At the very least, it means that you're thinking about and using theory.

The fifth is involved. What do you mean?
#12
does it always work by taking a pitch one half step down then the farthest sharp to the right to recognize key? or is there a better way????
#13
EDIT: to BGC

we are talking about the fifth of one scale becoming the root of another and shapening the b7th

where my mind just didn't register there and was thinking we are changing the 4th

but i know whats going on

that is where i got confused

and with that said i am going to sleep

You pretty much got it Adam....that's why it's call the CIRCLE of 5th.

As long as it works for you.
memeorizing the number of # or b didn't retain over the years. I Aced the test
But comprehending how it works...is better for me.

If you continue with the Circle
The 5th note of G is D.
The next key signature is the Key of D. The key of D has F# and C#
The C# is now the 7th posistion. The G is now in the 4th posistion.

The next key is A. A is the 5th note of D. The next # ro be added is G#
Obviously becuase of the formula you're using , Adam.

You can reverse this process. if you want to go to a key with less #

To cycle down to the Flat side of the circle of 5th.
Some people say Cycle down

Put the 4th note in the first posistion...Lower the 7th note 1/2 pitch.
Example...from C the F.

F becomes the root. C becomes the 5th....(a full step between 4 and 5)
Therefore the Bb in the Key of F

To translate that to my guitar.

I simply just make a Bar chord. C5...per say. Root and the 5th note.
it's down hill from there...the 4th is 1 step down from the 5th.

The short version
Circle to the 5th note and raise the 4th note....to the sharp keys
Cylce to the 4th note and drop the 7th note to the flat keys.

Remove the 4th and 7th..mmm you'll get something call pentatonic.
a pentagon has 5 sides i think.lol


No..it's not complicate at all.

Basically the circle of fifths, and you could keep going to D, then to A, then E etc. adding a sharp each time to get the right key sig.
