LESSON 12. Re-harmonization Techniques (1)

At the top left of the score:
The D flat will not change to C sharp due to enharmonic equivalence.
The E flat will not change to D sharp due to enharmonic equivalence.
The F sharp will not change to G flat due to enharmonic equivalence.
The A flat will not change to G sharp due to enharmonic equivalence.
The B flat will not change to A sharp due to enharmonic equivalence.
The valid notation is the one that appears at the top left in large letters; the one in small letters is not valid.
It is also important to consider that when playing chords with a wide range, sometimes the highest or lowest notes may not be on the score but can be observed on the keyboard displayed at the bottom of the screen.
