Flat (music) facts for kids
In music, flat, or Bemolle, means "lower in pitch." In music notation, flat means "lower in pitch by a semitone (half step)," and has the symbol (♭). The Unicode character '♭' (U+266D) is the flat sign. Its HTML entity is ♭.
Double flats also exist, which look like and lower a note by two semitones, or a whole step. Sometimes you will encounter half or three-quarter flats. The Unicode character '𝄫' 𝄫 (U+1D12B) represents the double flat sign.
A triple flat can be found, but it is very rare. It lowers a note three semitones.
In tuning, flat can also mean "slightly lower in pitch". If the same note is played on two instruments at the same time, the lower-pitched one is flat compared to the higher-pitched one.
