Under what condition are accidentals used beyond those in the key signature?

• A. They are used only when needed beyond those in the key signature.
• B. They are never used.
• C. They always indicate modulation.
• D. They must follow the key signature.

Answer: (A)

Accidentals exist to override the pitch indicated by the key signature when you need something different. They are used only when a note must be altered beyond what the key signature provides. This explicit sign tells the reader exactly which pitch to play for that note, for the rest of the measure (in that octave) until a barline or a canceling sign resets it. For instance, if the key signature makes F sharp, an F natural is shown with a natural sign to indicate the deviation from the baseline. If you later want F sharp again in the same measure, you’d write another accidental on that note. In the next measure, the key signature once more governs the pitch unless another accidental is written.
