as i had learned, the key of C major (based on the Ionian scale) consist no sharps or flat notes. the chords are:
C – Dm – Em – F – G – Am – Bm7b5 – C
and down here is the The Circle of Fourths Chart i made. i customized it so i can define and remember them.
what i can read from this chart is, from the apex, the key of C, then when you follow the blue guy on chart (clockwise), you will get the circle of fourths. the next note(THE FOURTH note, *that’s why it is called Circle of FOURTHS) after C major is F major. F major as root(1st) has 1 flat note in its chord sequence.
F – Gm – Am – Bb – C – Dm – Em7b5 – F
|F major key (1 flat-note: Bb)|
in the key of F major as root, there is one flat note, the one i colored with red, the Bb, … i’d like to put more images here to define all these since I’m not good at all in modifying text on blog post.
the next fourth note is Bb and when it comes to 1st or root, the Bb key in major has 2 flat notes:
|Bb Major Key (2 flat notes: Bb – Eb|
|Eb Major Key (3 flat-notes: Eb – Ab – Bb)|
|Ab Major Key (4 flat-notes: Ab – Bb – Db – Eb)|
|Db Major Key (5 flat-notes: Db – Eb – Gb – Ab – Bb)|
so this far i have defined C, F, Bb, Eb, Ab, Db as the major key with the number of flat-notes inside them. the latest one is F#/Gb as the major key, which i save it for the next part of this post with more explanations in it. for God’s sake, for just one circle, this post is way too long…. hahaha
