 So, a super quick and easy way to shift between chords would be, let's say if you take C major here in root position C, E, G, you ask yourself what is the next chord, so I want the next chord to be A minor and we are in luck because A minor just has one different note compared to C major. The G for the C goes to A of A minor and all you do is retain the positions of the common notes and change to the unique note with a finger which works for you. Write them all down in a circle and the circle gives you a list of three shapes. You can do it from A minor, journeying to maybe an F major, journeying to maybe a D minor, journeying to a B flat major, maybe a D flat major, an F major which I already did and then F minor maybe, D minor and then back to C. But if there is nothing in common, retain the shape or the inversion of the previous chord.
