Changing Note

Complexity : 3/10 (simple)

The changing note figure consists of a double appoggiatura with the principal note added at the beginning.
The lower note follows the same rules as in the double appoggiatura.
Changing notes can be used simultaneously in parallel 3rds and 6ths. The lower note must be either both diatonic or both chromatic.
If harmonically appropriate, a change of chord may be introduced in the third note of the figure.
