Bold font of chord in latex pkg. guitar

Question

I use the guitar package.

The documentation says I can redefine \guitarPreAccord command to change font size, but I want guitar chords to be printed in bold. I tried this and it didn't work:

\renewcommand\guitarPreAccord{\footnotesize\strut\textbf}

Answer 1

You need to use \bfseries in this case. See this post for an explainer.

\documentclass{book}
\usepackage{guitar}
    \renewcommand\guitarPreAccord{\footnotesize\strut\bfseries}
\begin{document}
\begin{guitar}
[Cm]This [Bb]is a [G#]very [Gm]simple song.
\end{guitar}
\end{document}
