Variation of meaning by geographical region
The referent of the musical note B varies by location.Template:Citation needed See Template:Format link for a discussion on other differences in letter naming of the notes.
In the United States, Canada, Australia, the United Kingdom, the Republic of Ireland, and the Netherlands, as described above, B usually refers to the note a semitone below C, while B-flat refers to the note a whole tone below C.Template:Citation needed
However, in Germany, Central and Eastern Europe, and Scandinavia, the label B is sometimes used for what, above, is called B-flat, and the note a semitone below C is called H. This makes possible certain spellings which are otherwise impossible, such as the BACH motif and the DSCH motif (the latter of which also uses the "S" name for what in Anglophone would be E-flat).Template:Citation needed
