降低 Leadsheets 中的基线跳跃

Question

如何才能降低包中的行间距leadsheets以使歌曲更紧凑？

\documentclass[a4paper]{book}

\usepackage{leadsheets}
\usepackage{lmodern}

\renewcommand\familydefault{\ttdefault}

% these values are too extreme, I know.
% they just serve to make the point more clearly visible
\setlength{\parskip}{0pt}
\linespread{0.4}
\setlength{\baselineskip}{2pt}

\begin{document}
    This text here works.

    It is spaced in a readable but space conserving manner.    

    \begin{song}{
        title={Example Song}
    }
        \begin{verse}
            In this verse, the lines have a big distance.

            They are separated with a blank line in the source code.
        \end{verse}
        \begin{chorus}
            These ^{Ab}lines have ^{C}chords, which should of ^{Ebmaj7}course use more ^{G}space than in the verse

            But they could ^{F}still be formatted with a ^{C}lower distance to each other
        \end{chorus}
    \end{song}
