Sharps and Flats

The black keys on a piano keyboard can referred to as either sharps or flats. Sharps and flats are also called accidentals.


Accidentals are symbols used to raise or lower notes by half steps. A half step is the distance between two adjacent keys on a piano keyboard.

Sharp ( ♯ ) is an accidental that raises a note by a half step.
Flat ( ♭ ) is an accidental that lowers a note by a half step.

Double Sharp is an accidental that raises a note by a whole step (two half steps).
Double Flat is an accidental that lowers a note by a whole step (two half steps).

A Natural (♮) is an accidental which cancels out any previous accidentals.
