Webster's 1913 Dictionary
\B\ (b[=e])
is the second letter of the English alphabet. (See Guide to
Pronunciation, [sect][sect] 196, 220.) It is etymologically
related to p, v, f, w and m, letters representing sounds
having a close organic affinity to its own sound; as in Eng.
bursar and purser; Eng. bear and Lat. ferre; Eng. silver and
Ger. silber; Lat. cubitum and It. gomito; Eng. seven,
Anglo-Saxon seofon, Ger. sieben, Lat. septem, Gr."epta`,
Sanskrit saptan. The form of letter B is Roman, from Greek B
(Beta), of Semitic origin. The small b was formed by gradual
change from the capital B.

Note: In Music, B is the nominal of the seventh tone in the
      model major scale (the scale of C major ), or of the
      second tone in it's relative minor scale (that of A
      minor ) . B[flat] stands for B flat, the tone a half
      step, or semitone, lower than B. In German, B stands
      for our B[flat], while our B natural is called H
      (pronounced h["a]).
