Woud it be possible to have more than 2 lines for the initial ?
I tried a workaround with wrapfigure, which sounds promising, but the length of the lines doesn't adjust, so they get out of margin :

\documentclass[12pt]{article}

\usepackage{gregoriotex,libertine,wrapfig}

\begin{document}

\begin{wrapfigure}[3]{l}{0.25\textwidth}
{\fontsize{120pt}{140pt}\selectfont I}
\end{wrapfigure}
\makeatletter\gre@noinitial\makeatother

Perhaps it could be related to #1418

This is something that's been on my ideal list of features for a while now, but I've not had a chance to work on it. Right now the readjustment of the line length that is necessary after the initial is handled within the manual line breaks and so it's necessary for the gabc code to contain multiple z or Z in order for multiline initials. I'd like to move that into the automatic line breaking mechanisms to remove this dependency and make it (and the placement of the initial) more responsive to setting \gresetinitiallines to numbers higher than 2.

There is, however, a work around for now. If \gresetinitiallines{2} is set, then the first "line" of the score can actually be more than 1 line of the score. The initial's vertical placement has to be adjusted manually using initialraise but it's possible to simulate a 3 (or more) line initial in a fragile way:

\documentclass[12pt]{article}

\usepackage{gregoriotex,libertine,wrapfig}

\grechangestyle{initial}{\fontsize{200pt}{0pt}\selectfont}
\newdimen\initialwidth
\initialwidth=0.25\textwidth
\grechangedim{manualinitialwidth}{\the\initialwidth}{scalable}
\grechangedim{initialraise}{-25pt}{scalable}
\gresetinitiallines{2}
