The symbol ♭♭ (double flat) that appears in sheet music means to lower a note by two semitones (a whole tone).
In this article, we’ll explain in detail what a double flat means, how it’s used, and provide examples from actual piano performances!
What is a Double Flat (♭♭)?
A double flat (♭♭) is a musical symbol that lowers the original note by a whole tone (two semitones).
- A with a double flat becomes a G.
- B with a double flat becomes an A.
When you see a double flat in sheet music, remember to apply the rule: “lower the note by a whole tone.”
How Double Flats Differ from Other Accidentals
There are several symbols in sheet music used to alter pitch. Here’s a simple overview of the differences:
- Sharp (♯): Raises the note by a semitone
- Flat (♭): Lowers the note by a semitone
- Natural (♮): Cancels any previous sharps or flats
- Double Sharp (
): Raises the note by a whole tone - Double Flat (♭♭): Lowers the note by a whole tone
The double flat consists of two flat symbols and is used to lower the pitch even more than a single flat.
