Have you ever seen the circle of 4ths (circle of 5ths if you go the other way around the circle).

C
F G
Bb/A# D
Eb/D# A
Ab/G# E
Db/C# B
Gb/F#

If you go around clockwise it's 5ths, counterclockwise is 4ths. The relative minor is 3 clockwise steps around the circle.

Furthermore, from a key signature/scale standpoint, as you go clockwise, you're adding a sharp to the scale, as you go counterclockwise, you're adding a flat to the scale...to wit: the key signature for C is blank...no sharps, no flats, G is one sharp, D is two sharps, etc. F is one flat, Bb is two flats etc. The sharps and flats meet at Gb/F# which is six flats or six sharps, either way you want to make your eyes burn (that also means that legally, you could use 7 flats to denote the key of B, but while legal, it's probably immoral).

Now, what you're talking about is another way of speaking of "Modes." I can't tell you one mode from another, but I do know that in essence, a mode is a scale, for example C-D-E-F-G-A-B-C is C Major, also known as C Lydian (? I think that's the right mode). There are other modes such as Mixolydian, Aeolian and a bunch of others. If you play C-D-E-F-G-A-Bb-C it makes it a C Mixolydian (? maybe), in actuality of course it's either an F major that starts and stops on the 5th, or a D minor that starts and stops on the 7th, depending on what you want to call it.

They're all just different ways of describing the scales. The Key signatures tell you what notes of the scale are flatted/sharped.

When I'm soloing I think very little about scales, and modes. I do try to remember what key we're in and the chord that's being played, but I don't really specifically think about it, it's more of a thing to keep in the back of your mind as you're playing.

Theory should free up your playing, not clutter it with cumbersome rules....practice theory at home and play from the ears and the gut when you're on a job.

I hope this gives you something to use.


: I would like to know if anyone has approached the guitar this way. I am self-taught so I don't know ALL the lingo. Anyway I have a question on improvisational soloing. Say we are playing in A Major, I am playing in an AMaj Scale, then the song goes to a F#m (the vi chord in the key). The minor scale in F#m are the same notes as in AMaj. Now say that the chord changes to a DMaj (the IV chord) I notice that all the notes are the same except there is a flat 7. Also if the chord changed to a ii (Bm) the minor scale would be just the same as the A Major scale except for a flat 7. Then there is the iii and V chords (C#m and EMaj). The only difference in these scales are a sharp 4. (ie. E Major scale, C# Minor scale). Has anyone else noticed this (I'm sure it's in a book somewhere on this planet). I am wondering if an experienced player out there uses this to their advantage (like when the "chord of the moment" changes to a V chord, you would move all of your 4's sharp, then switch back to normal after you get back to the Root chord). I don't know if any of this makes sense to anyone else but myself, but if it does, I would like to hear how others use this to play, or if I'm missing something. Thanks,
