Two flats placed before a note indicate to lower the note by a whole step. What is this accidental called?

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

Answer: (B)

In music notation, an accidental alters a note’s pitch. A single flat lowers the pitch by one semitone. When you see two flats in front of a note, that is called a double flat, and it lowers the pitch by two semitones—a whole step. The symbol is two flat signs side by side, written as Cbb, Fbb, etc., preserving the letter name while changing the pitch accordingly. For example, C double flat sounds the same as A natural, even though it’s still spelled as Cbb for proper musical spelling. This naming helps maintain correct scale and harmony spellings in different keys, while the sounding pitch matches the intended chromatic alteration.
