MY title page looks like this now:
\documentclass{beamer}
\begin{document}
\title{The title}
\author{The author}
\date{\today}
\frame{\titlepage}
\end{document}
I want to add one more line, and I don't know how to do it. I found the \institute command, but it is not suited for me.

There are multiple ways to add an additional line with a consultant to the title page.
You can add a line break inside of the
\author{•}
macro with an additional space. As a consultant in a sense belongs to the author I would prefer this way.If you don't need an institute on the title page, you can also use the
\institute{•}
macro (or any other field you don't need) and adjust the font size if desired.And if these simple ways still do not satisfy your needs you can always redefine your title page as described here.
