3. Key
This window indicates the keys to which the pivot chord belongs. Major and
minor keys are differentiated by color.
4. Chord Degree
The Roman numerals indicate the chord degree of the pivot chord as it relates to
the key that appears in the key indicator window. In other words, the chord
degree tells what position the pivot chord plays in the key that is being displayed.
Example #1:
This shows C major as the pivot chord. While C major is the I (one) chord in the
key of C major, in the key of G major it is the IV (four) chord.
Example #2:
This shows C minor as the pivot chord. While C minor is the Im (one) chord in
the key of C minor, in the key of E< major it is the VIm (six) chord.
