Tweaking placement of rehearsal marks

[Nick Didkovsky]

Hello

I am using \mark in my first measure to give instructions on the feel of 
the piece. The mark's text overlaps some beams and some notes on the 
various parts when they are printed individually. 
How can I tweak to avoid overlapping?

The commands I am using are:
\once \override Score.RehearsalMark #'self-alignment-X = #left
\mark "Smooth, light, precise"

Thanks
