Thanks Leo ! That way, I'll be fumbling more efficiently next time I'm trying to do something ^^
Hi Claire!
There is also another mistake in your code:
When you use \override it’s supposed to be followed by a Grob name and the property that’s going to be overridden, like
\override Stem.direction = #UP
When using the commands \stemUp and \stemDown you just write for instance
\once \stemUp, without \override
