Variation of meaning by geographical region

The referent of the musical note B varies by location. See note 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.

However, in Germany, Central and Eastern Europe, and Scandinavia, the label B is 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.
