Flat (music)

The B or Be ( ♭ ) referred to in the notation of music the humiliation of a Stammtons by a semitone. The character has roughly the shape of a stylized lowercase letter b. The character is written either on a line or space of the staff, and altered the standing on this pitch tone. If the degrading tone to on an auxiliary line, so loading is placed before the auxiliary line.

On the note names of the altered tone the ending- it is appended. Exceptions: H to B, E to There 's A Will to As.

The symbol is used in two ways:

  • As accidentals, it is right in front of a particular note; it is only in that cycle in which it is listed, and only for the designated octave
  • As a sign it is immediately after the clef and applies either to the end of the piece, or until it is resolved by other signs; it also applies to all octave ranges


In the older chant notation formed from the 10th century, initially only two accidentals out, which always refer to the Stammton B: the b rotundum or b molle ( "round B" ) refers to the lower Tonvariante, the b quadratum or b durum ( " square B") higher. The designation b molle, the foreign names bemolle ( Italian) or bémol (French ) and the name of the minor Tongeschlechts derived.
