Captain's Log, November 5th, 2012Mates, I want to draw the most important conclusions from last week's chit chattering and prepare you for the next set which I'll post tomorrow:
Ways to navigate the circle:
- If we go clockwise, we discover the apparition of sharps and that each note is followed by its 5th
- If we go counter-clockwise, we will discover the apparition of flats
You can use a funny sentence to remember the disposition of the notes on the circle:
- clockwise, such as 'Fat Cows Go Down Around Every Barn' or, my favorite: 'Frankly, Cool Guitarists Do Absolutely Everything Better'
- counterclockwise: 'Boiled Eggs Are Darn Good'
You can find which are the sharps in each key, if you know that starting with the first one (G major) each major seventh is a sharp and it adds the previous found ones until you reach F#
If you want to get rid of the nasty notes, which inevitably appear once you reach F# on the circle, simply transform F# into Gb and you will start losing alterations as you continue to navigate the circle, clockwise.
You can find out which flats disappear after transforming F# into Gb, by simply looking at the next key after Gb and considering its major 7th as an unaltered note. For instance, in the case of the Db major scale - Cb would be the major 7th, but it will transform itself into C. If you don't believe me, apply the major scale formula for Db and you'll see
The same goes until we reach C major and there are no more alterations!
You can discover a progression just by knowing the relationships between the notes on the circle
Clockwise: F C G D A E B means IV I V ii vi iii vii
Counterclockwise: C F Bb Eb Ab Db Gb means I IV bvii biii bvi bii bV
Now, imagine that if you decide to make ANY note a root note for a major scale and you harmonize the notes so that you may obtain chords, the above relationships remain valid, whatsoever
We'll discuss more on Thursday!
You can also discover the notes making up a scale for instance
Check out the upper right region of the circle and think of C as the root note - what do you discover? C G D A E - these are the scrambled notes of the C major pentatonic scale! Formula: 1 2 3 5 6. Notes: C D E G A
It's valid in the order discovered above, for EVERY root note
More to come...
See you this Thursday at 8 PM London time!
