<p>The diagrams are correct.</p>
<p>Read the third item in the list of [http://en.wikipedia.org/wiki/Helmholtz_pitch_notation#Variations|Variations] in the Wikipedia article titled [http://en.wikipedia.org/wiki/Helmholtz_pitch_notation|Helmholtz pitch notation]. I chose to use this variation of Helmholtz pitch notation in my example Perl script because it seems more well-suited to computer use and digital typography. One thing that troubled me is that there are no Unicode characters that are <i>low</i> versions of the <i>high</i> prime characters: PRIME U+2032 (′), DOUBLE PRIME U+2033 (″), TRIPLE PRIME U+2034 (‴), etc.</p>
