When a note’s pitch is reduced by two semitones (two half steps), the symbol B double flat represents the pitch B double flat, which is reduced by two semitones (two half steps). A double-sharp note, an E double-flat note, or a D double-flat note are all enharmonic equivalents. A double-flat note is the same key as an E, but the piano keyboard has a D key instead of a double-flat note. When the C double- sharp key is played on a piano keyboard, the D key is played higher than the C key. Unless there is a tie across the barline, the double flat has no effect on notes after the measure has ended. It is always true that a double-flat is only indicated by two flat signs, regardless of whether the key signature is present. The pitch of the note attached to a musical piece is altered by the rotation of a double flat symbol, as well as any subsequent occurrence of the same note in the same measure. A extraterrestrial note is one that has multiple names but is played with the same key. This symbol, like other accidental symbols, is used in music notation. This is indicated by the symbol “bb”, which stands for “bemolle” in Italian.Ī double flat sign is the opposite of a double sharp sign, which lowers a note’s pitch by two half steps. Double flats are also sometimes used to lower the pitch of a note by a whole tone, or two semitones. This is often abbreviated as “8va”, which stands for “ottava bassa” in Italian. In piano music, a double flat may be used to indicate that a note should be played two octaves lower than its normal pitch. It is typically used to indicate that a note should be played two semitones lower than its normal pitch.

A double flat is a symbol in music notation that lowers a note by two semitones, or one whole step.
