When the I chord is male the IV and V chords (the other two major chords) are also male,

except

D major where the IV chord is neuter, and

B major where the V chord is neuter.

When the I chord is male, the IV and V chords (the other two major chords) are also male.

The minor chords – II, III and VI are female, except

D major where the IIm chord is neuter (n1). and

B major where the IIIm chord is neuter (n2).

Common or shared notes

Each note of the scale is shared by three chords.  It is the root of one chord, the third
of one chord, and the fifth on one chord.  Take advantage of this.  It helps when
the chord that you are changing to shares a note with the current chord. The next chord
will either use one or two notes from the current chord or an adjacent note.
