+% \paragraph{Tablatures Within Macros}
+% Macros that produce tablatures must not bury the colons that separate the
+% \Meta{fret}, \Meta{strings}, and \Meta{fingering} arguments within other
+% macros, and it's safest to always include both colons to avoid ambiguities
+% related to optional argument parsing.
+% For example,
+%
+% \begin{codeblock}
+% |\newcommand{\mystrings}{X4412X}|
+% |\newcommand{\myfingers}{X3412X}|
+% |\newcommand{\mychord}{|\mac{gtab}|{C|\mac{shrp}|}{:\mystrings:\myfingers}}|
+% \end{codeblock}
+%
+% \noindent
+% works as expected.
+% But omitting the colon before |\mystrings| in the definition of |\mychord|
+% confuses \mac{gtab} into thinking |\mystrings| is the \Meta{fret}
+% argument, and writing code like |\gtab{C\shrp}{\allargs}| with |\allargs|
+% defined to something with colons results in an error, because it confuses
+% \mac{gtab} into thinking that |\allargs| is only the \Meta{strings} argument.
