The Cycle or Circle of Fifths is better referred to as the Cycle or Circle of Sevenths. The reason for this is that when you modulate or when you use the VII,III VI,II,V,I progression you are generally using dominant seventh chords. The dominant seventh chord is an active chord that propels you into the next key. Jazz musicians often use the IIm7 to V7 chords to modulate.

The best way to learn the sharps and flats of diatonic major scales is to sing them through from C----C# or from C----Cb.

C7 moves actively to F7, F7-to Bb7 etc...................
