Cycle of fourths

Hi!

Today let's talk about the cycle of fourths (or fifths). It is a figure that helps us understand the relationship between the twelve tones of the chromatic scale.

Starting from any note (we choose C to simplify), it is possible to run through the whole chromatic scale going up fourths (clockwise) or down fifths (anti-clockwise). This cycle is often shown differently(going up fifths in a clockwise motion). But as ascending fourths are found everywhere in jazz tunes (and in music in general; it's like a gravitational energy) let's learn it this way.

This circle is useful:
-To know the key signature of any tonality (sharps and flats)
-To get used to the ascending fourths motion

It is important to practice any scale, arpeggio, chord, phrase in every key following this circle! This gives you a better understanding and flexibility in any key.

N.B. : in the chromatic scale, there is no semitone between B-C and E-F, hence the absence of E#, Fb, Cb or B# keys.

Have fun!

Arpeggios!

Here are the four most important arpeggio types.

Major 7 : 1-3-5-7
Dom. 7 : 1-3-5-b7
Min. 7 : 1-b3-5-b7
Min.7 b5 : 1-b3-b5-b7

They're divided in columns : 6-1 means sixth string, first finger (first finger plays the root note). 4-2 means fourth string, second finger, etc.

Some of these positins are less "guitar-friendly" than others but check them all before making a choice!
It is rather important to situate the third, fifth and seventh in these arpeggios. A good way to practice them is to play over "Bluesette" or "All The Things you Are" changes, trying to stay in one position using these arpeggios. Good luck!
