Since the new 2012 edition of the book, CVI has changed its pitch notation from Helmholz to Scientific pitch notation, “which means that the middle C’s (formerly called C1) is now called c4.” (Danish 2012 edition, p. 10). So the chart on top of this page is in need of revision, as it is no longer up-to-date.
Personally, I really appreciate the change to Scientific pitch notation, as it for me is more intuitive to understand and use than the old system
