Which symbol raises a note by a full step?

Which symbol raises a note by a full step?

• A. Sharp
• B. Natural
• C. Double Sharp
• D. Double Flat

Answer: (C)

Raising a note by a full step means lifting its pitch by two semitones. Accidentals modify pitch in predictable ways: a sharp adds one semitone, a natural cancels any prior alteration and returns to the unaltered pitch, and a double sharp raises by two semitones. So the symbol that represents increasing by a whole step is the double sharp. For example, F with a double sharp sounds as G natural, though it’s written as F double sharp to keep the correct spelling in the musical context. The other symbols do not reach two semitones upward: a single sharp moves up one semitone, a natural does not raise the pitch, and a double flat lowers by two semitones.
