B double flat
The musical note "B" preceded by two flat (♭♭) symbols. The effect of each flat symbol (♭) lowers the pitch of the indicated note a semitone (or a half step), so B double flat is the pitch "B" lowered by two semitones (two half steps). The resultant pitch would sound the same as the pitch "A".
